Solve the equation for all values of x by completing the square.
x^2 + 6x – 27 = 0

Answers

Answer:

Solution

=3

=−9

x=3

x=−9

x=3x=−9

Step-by-step explanation:

Boom

Answer:

x=-9 and 3

Step-by-step explanation:

FOIL method

x^2+6x-27=0

Find the common numbers that multiply to 27 that will also equal 6.

(27x6) or (9x3)

the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.

then FOIL them

(x+9)(x-3)

FIRST:  x*x=x^2

OUTSIDE: x*-3=-3x

INNER: 9*x=9x

LAST: +9*-3=-27

x^2(-3x9x)-27

x^2+6x-27

now that the equation matches you solve for x.

(x+9)=0  x=-9

(x-3)=0   x=3

Evaluate the equation.

Archer Middle School has 78 students playing soccer this year. This number is 6 more than 3 times the number of students who played last year. Let n represent the number of students who played last year. Which equation expresses an equality between two different ways of expressing the number of students who are playing soccer this year?

A: n + 6 = 78
B: 3n + 6 = 78
C: n - 6 = 78
D: 3n - 6 = 78

Answers

The answer is B. This is because we know this is 6 more than 3 times the number of students that played last year. A and C makes no sense. D does not make any sense because it is 6 more not 6 less.
b is the answer bc you are adding the 6 and multiplying the 3 with the variable

Step-by-step explanation:

Im not really sure but you can tell they have a pattern, for instance a square and triangle have sides while a circle and oval do not.

At the 50th place, triangle shape pattern is used.

What is a triangle?

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of the angles of a triangle is always 180°

The square, triangle, circle, and oval pattern rules are listed.

The formula for the number of shapes (n) is:

In order to calculate the 50th shape, the following absolute operator is used,

Divide 50 by 4 and record the result,

4 divided by 50 leaves, 2 as the remaining.

This implies that, the shape at the 50th position is the same shape at the 2nd position.

In the 2nd position, the shape is circle, triangle.

Hence, the shape is triangle.

4(2y + 1)

Distributive property

Step-by-step explanation:

8y + 4

We can factor out a 4 out of both as both are divisible by 4

8y / 4 = 2y

4 / 4 = 1

So 8y + 4 is the same as saying 4 * 2y + 4 * 1

This can be written as 4(2y + 1) which is written using the distributive property

Douglas went to Charlies General Store to get gas. He paid $52.20 for 20 gallons of gas. How much would he have paid if he got 25 gallons instead

Answers

Answer:

65.25

Step-by-step explanation:

52.20 is the total for 20 gallons of gas

we divide 52.20 by 20 to find out the price per gallon.

52.20/20= 2.61 per gallon

for 25 gallons --> 2.61 x 25 = 65.25

answer: $65.25

explanation:
$52.20 divided by 20 equals $2.61 per gallon if you multiply that by 25 gallons you will end up with $65.25

Problem 3: Just 33 draw 4 boxes of 11 and one with 11

Problem 4: 30
Problem 5: Naomi

Step-by-step explanation:

For problem three since you are multiplying the same equation by 4 its basically (2+9)+3(2+9) so you can just cancel out the 2+9 from both and you are left with 3(2+9) which is just 33

For problem 4 100-(12x4)=52 and 10+(3x4) = 22 and when you subtract the two (52-22) you get 30

For problem 5 you get 18 with your equation and so since Carlos' equation gets 9 and Miranda gets 24 and Will gets 35 the only one left is Naomi which also gets 18 just like you.

It’s number A because it shows the number of tulips she plants is 4 more than half of the number of daises

The expression that represents the number of tulips Pia planted is option A. x/2 + 4.

What are Expressions?

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given that,

Number of daisies planted is represented by x.

Number of tulips planted is 4 more than half the number of daisies.

Half the number of daisies is x/2.

4 more than half the number of daisies is x/2 + 4.

Hence the number of tulips planted is given by the expression x/2 + 4.

Answer: 4.416 (the 6 should have a line on top to show it goes on)

Step-by-step explanation:

which expression means “6 more than the quotient of a number and 5”

Answers

The answer is B because I did the the test you are doing

x/5+6 =>  expression means “6 more than the quotient of a number and 5”.

Option B is correct.

Here,

The expression that means "6 more than the quotient of a number and 5" can be written as:

(x / 5) + 6

In this expression, "x" represents the unknown number.

Let's break down the expression and explain it step by step:

(x / 5):

This part of the expression represents the quotient of "x" and 5.

It means that we divide "x" by 5.

(x / 5) + 6:

his means we take the quotient obtained in step 1 and add 6 to it.

It represents "6 more than the quotient of a number and 5."

Hence, x/5+6 =>  expression means “6 more than the quotient of a number and 5”.

Option B is correct.

Relative to ground level, what is the elevation of the hole after placing the shrub in the hole? Enter your answer as a mixed number in simplest form by filling in the boxes.

Answers

Answer:

15/6

Step-by-step explanation:

(20/9) ft of the hole is elevated after the shrub was placed.

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problem

Given is that Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole.

In 15 minutes, the depth of hole digged is (2/3) feet.

In 1 minute, the depth of hole digged is {(2/3)/15} feet.

In 60 minutes, the depth of hole digged will be {(2/3)/15} x 60 = 8/3 ft.

The hole filled after placing the shrub will be -

(5/6) x (8/3)

5/6 x 8/3

5/3 x 4/3

20/9

Therefore, the (20/9) ft of the hole is elevated after the shrub was placed.
