Answer:
Step-by-step explanation:
x2 + 5x + 4 (the area of the rectangle)
x + 2 (the length of one side)
(x2 + 5x + 4)/(x + 2)
do a division of this polynomial and you get; (x + 3) - 2/(x+2), you could leave the answer like this or you could simplify by using the LCM method
= [(x+2)(x+3) - 2]/(x + 2)
checking; (x + 2)*[(x+2)(x+3) - 2]/(x + 2) = (x+2)(x+3) - 2 = x2 +5x + 6 - 2 = x2 +5x + 4 (proven)

Step 2: Solve for t
Divide 7 on both sides: -14 = tRewrite: t = -14Step 3: Check
Plug in t into the original equation to verify it's a solution.
Substitute in t: -98 = 7(-14)Multiply: -98 = -98Here we see that -98 is equal to -98.
∴ t = -14 is the solution to the equation.

What is the difference x/x^2+3+2 - 1/(x+2)(x+1)
Answer:
#4, x-1/(x^2+3x+2)
Step-by-step explanation:
x/(x^2+3x+2) - 1/((x+2)(x+1))
Convert the 1/((x+2)(x+1)) to 1/(x^2+3x+2)
now you have a common denominator to subtract
x/(x^2+3x+2) - 1/(x^2+3x+2)
results x-1/(x^2+3x+2)
Im stuck on this problem. Will give 20pts to whoever answers it!
Answer:
a ≈ 13.1
c ≈ 13.8
Step-by-step explanation:
set up proportions based on corresponding sides:
17 = 13
a 10
13a = 170
a ≈ 13.1
18 = c
17 13

Step-by-step explanation:
im smart
can you guys help with 1-3
Answer:
1. y = 1/3x - 1
2. y = 2/5x
3. y = x + 8
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + c
where m is the slope and c is the y-intercept
So, we have the following based on the supplied values;
1. y = 1/3x - 1
2. y = 2/5x
3. y = x + 8
Is this right or no caused I just wanna make sure
===================================================
Work Shown:
2x+3y = 18
3y = 18-2x ..... subtract 2x from both sides
3y = -2x+18
y = (-2x+18)/3 .... divide both sides by 3
y = (-2x)/3 + 18/3
y = (-2/3)x + 6
-----------
As a quick shortcut, anything in the form Ax+By = C will convert to y = (-A/B)x+(C/B) when you solve for y.
The slope is -A/B and the y intercept is C/B
If the surface area of a sphere is 144pi square centimeters, what is the length of the radius of the sphere, in centimeters
Answer:
6cm
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
From the Question, we are given:
The surface area of a sphere = 144pi square centimeters = 144π cm²
The length of the radius of the sphere, in centimeters is calculated by:
4πr² = 144π
Divide both sides by 4π
4πr²/4π = 144π/4π
r² = 36
Square root both sides
√r² = √36
r = 6cm
Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.
Work out the volume of this sphere.
Give your answer to 1 decimal place.
Spheres
Vol = ar
19 cm
Answer:
The volume is;
3951.8 cm^3
Step-by-step explanation:
As we can see, the sphere diameter is 19 cm
Radius is half of this which is 19/2 = 9.5 cm
Putting this in the area , we have
4/3 * 3.142 * 9.5^3 = 3951.8

Casey buys a bracket for. She pays for the bracelet and pays $0.72 in sales tax. The sales tax is 6%. What is the Original price for the bracelet, before tax
Answer:
$12
Step-by-step explanation:
amount of tax = $0.72
percent of tax= 6%
Let the original cost be x
so that
6% of x= 0.72
solve for x
6/100*x= 0.72
0.06x= 0.72
divide both sides by 0.06
x= 0.72/0.06
x=$12
Hence the cost is $12

Answer:
d) 20
Step-by-step explanation:
To find possible side lengths use the triangle inequality theorem. The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. So for the measurements 6, 11, 20 to make a triangle 6+11 must equal at least 20, which isn't true. Therefore, 20 cannot be a measurement for this triangle.

What is the exact and approximate area of a circle with a diameter of 6 feet? For the approximate area, round your answer to the nearest tenths place.
Answer:
C = pi * d calculates the circumference (distance around the outside of the circle). D in the formula refers to the diameter which is the width of the circle. The formula for the area of a circle is A = pi * r * r where r is the radius (diameter / 2).

how far can you run in 5/7 of a hour if you run at a speed of 8 2/5 miles per hour
Answer:
6 miles
Step-by-step explanation:
At a speed of 8 2/5 miles per hour, you can run a distance of 6 miles
How to find distanceSpeed = 8 2/5 miles per hourTime taken = 5/7 of a hourDistance = xSpeed = distance / time taken
8 2/5 = x ÷ 5/7
42/5 = x ÷ 5/7
cross product
42/5 × 5/7 = x
x = (42×5) / (5×7)
= 210/35
= 6 miles
Therefore, you can run a distance of 6 miles at a speed of 8 2/5 miles per hour
