Let x is the side of the square
so A = x * x or A = x^2 = 36
As you know 36 is a perfect square root = 6^2
Then x = 6 cm
Perimeter = 4x = 4(6) = 24 cm
The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.
So when you look at f(-2), find the Y value where the line crosses.
At X-2, the line crosses Y at -2
At X = 2, the line crosses at Y = 2
At X = 4, the line crosses at Y = 1
The answer is -2,2,1
A and D
should be the answers.
For an eqtuaion wih slope m and goes through point (x1,y1)
equation is
y-y1=m(x-x1)
so
point (-1,6)
slope=-3
y-6=-3(x-(-1))
y-6=-3(x+1)
2nd one
Answer:
13.5
8.64
Step-by-step explanation:
1) 9/100 * 150 = 13.5
2) 12/100 *72= 8.64
it means if some thing represents 9 of 100 , so by how much will it represent of a certain number (ex: 150)
