Answer
(y-8)x(3y^+7)
Step-by-step explanation:
3y^2(y-8)+7(y-8)
(y-8)x(3y^+7)
Answer:
A = 400 cm^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
80 = 4s
Divide each side by 4
80/4 = 4s/4
20 =s
We want to find the area of the square
A = s^2
A = 20^2
A = 400 cm^2
If the area is 120, each length is root(120)
root(120) = 2*root(30)
so the perimeter is:
4 * 2 * root(30) = 8 root(30)
which is approximately 43.8
Answer:
x = -11
Step-by-step explanation:
Considering tripled means multiplied by 3 because of tri, we know that we can use the equation 3x = -33.
To solve this we can divide both sides by 3:
3x = -33
x = -11
This gives our answer of -11.
X is 16 so turn everything into a equation
