Answer:
f(x) = -x^2 + x + 12.
Step-by-step explanation:
f(x) = a(x - 4)(x + 3) as the x-intercepts are -3 and 4.
a is some costant.
At the y intercept x = 0 so we have:
y = 12 = a(0-4)(0+3)
12 = -12a
a = -1
So our eaution is f(x) = -(x - 4)(x + 3)
= -(X^2 - x - 12)
= -x^2 + x + 12

On a farm there was a cow. And on the farm there were 2 sheep. There were also 3 chickens. What is the total mass of the 1 cow, the 2 sheep, the 3 chickens, and the 1 farmer on the farm?
Make a conjecture about how many ants might be on the farm. If you added all these ants into the previous question, how would that affect your answer for the total mass of all the animals?
What is the total mass of a human, a blue whale, and 6 ants all together?
Which is greater, the number of bacteria, or the number of all the other animals in the table put together?
The total mass of the living things on the farm is 588 kg.
Mass calculationSince on a farm there was a cow, 2 sheep and 3 chickens, to determine what is the total mass of the 1 cow, the 2 sheep, the 3 chickens, and the 1 farmer on the farm, the following calculation must be performed :
(6.2 x 10) + (4 x 10 x 10) + (2 x 6 x 10) + (3 x 2 x 1) = X62 + 400 + 120 + 6 = X588 = XTherefore, the total mass of the living things on the farm is 588 kg.

What are all the values of x that make the inequality 8 - 3x < 20 true?
Let's solve this inequality.
First of all, subtract 8 from both sides:-
[tex]\sf{-3x < 20-8}[/tex]
[tex]\sf{-3x < 12}[/tex]
Divide both sides by -3:-
[tex]\sf{x > -4}[/tex]
Notice that the inequality sign changed...
Here's the rule:-
When you multiply/divide both sides by a negative number, you flip the inequality sign; so if we have "less than" it becomes "greater than" and so on...
So these are the values of x that will make the inequality true:-
[tex]\bigstar{\boxed{\pmb{The~numbers~greater~than~-4}}}[/tex]
Well, -3 is greater than 4 :)
Let's plug it in and see if it makes the inequality true:-
-3>-4
Yes, it does make the inequality true :)
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Perimeter of Flat ShapesGiven Data
Diagonal = 850 meterSide of fence = 700 meterShape of land = SquareSince the shape of the land is that of a square
All the sides will be 700 meter
Dividing the land into two pieces, the side will be

Express each of the following rational numbers in power notation
(i) -1/125
Answer:
[tex]\displaystyle \large{-5^{-3}}[/tex]
Step-by-step explanation:
Given:
[tex]\displaystyle \large{-\dfrac{1}{125}}[/tex]
Convert to exponent using the laws of exponent:
[tex]\displaystyle \large{\dfrac{1}{a^n} = a^{-n}}[/tex]
That means we must find the base and exponent for 125, which is [tex]\displaystyle \large{5^3}[/tex]:
[tex]\displaystyle \large{-\dfrac{1}{125} = -\dfrac{1}{5^3}}[/tex]
From the law of exponent:
[tex]\displaystyle \large{-\dfrac{1}{5^3} = -5^{-3}}[/tex]
Therefore, the solution is [tex]\displaystyle \large{-5^{-3}}[/tex]

A rectangle has an area of 54 sq. cm and a length of 6 cm. Find its width
Answer:
9 cm
Step-by-step explanation:
A= lw
54=6w
9=w
Answer:
9 cm
Step-by-step explanation:
⇒ Area of rectangle = (L)(B)
Substitute the length, breadth, and the area in the formula:
⇒ Area of rectangle = (L)(B) = 54 cm²
⇒ (6)(B) = 54 cm²
Divide 6 both sides:
⇒ (6)(B)/6 = 54/6 cm²
⇒ B = 9 cm
Thus, the measure of the width is 9 cm.

fully explain why, in general, (a + b)^2 = a^2 +b^2.
No this is not correct identity
(a+b)²(a+b)(a+b)a(a+b)+b(a+b)a²+ab+ba+b²a²+2ab+b²Hence it's wrong
Answer:
Below!
Step-by-step explanation:
Let's simplify each side to determine if both sides are equal.
Left hand side of the equation:
Expression: (a + b)²This expression can be simplified using the rule (x + y)² = x² + 2(x)(y) + y².
⇒ a² + 2(a)(b) + b²When opening the parenthesis, we get;
⇒ a² + 2ab + b²This expression cannot be simplified further as there are no like terms in the expression obtained.
Right hand side of the equation:
Expression: a² + b²This expression cannot be simplified further as there are no like terms in the expression obtained.
Given equation:
(a + b)² = a² + b²This can be rewritten as;
a² + 2ab + b² = a² + b² (False)Therefore, it is impossible for a² + b² to be equivalent to a² + 2ab + b².

The area of a rectangle is 56 cm. The length is 2 cm more then x and the width is 5 cm less than twice x. Solve for x. ROund to the nearest whole number.
Answer:
x^{2} -3x=46
Step-by-step explanation:
First, we know that the area of the rectangle is L x W.
[tex]L= x+2\\W= x-5\\(x+2) * (x-5)=56[/tex]
So, we would get [tex]x^{2} -5x+2x-10[/tex]=56

Noah is making grilled cheese sandwiches for friends. He has 24 ounces of cheese. He plans to split the cheese evenly between 6 sandwiches.
Write an equation to determine how many ounces of cheese, ccc, Noah can use on each sandwich.
Answer:
24 / 6 = ccc
Step-by-step explanation:
There is 24 oz of cheese total that will be split evenly (divided) into 6 parts.
Each part will equal one sandwich worth of cheese (ccc) on the other side of the equation.
This one is very simple to solve, you could just calculate 24/6 to get your answer. But I'll go through it using typical algebra you would use for a less simple equation.
To solve:
Multiply by 6 to cancel the division by 6 on the left side
24 = 6ccc
Divide by 6 to isolate ccc again
4 = ccc
So each sandwich would get 4oz of cheese.
