Solve for y like the top equation:
2y = -4ax + 11
2y/2 = -4ax/2 + 11/2
y = -2ax + 11/2
Answer:
16
Step-by-step explanation:
Use a special rule: BD^2=AD*DC (the squared height in right triangle drawn to hypotenuse is equal to the product of the parts of hypotenuse on which height divides the hypotenuse) 12^2=9*DC
DC=16
Answer:
So, what you want to do first is add the height together.
5+5+5+5= 5*4=20
Then use the formula for finding the surface area of a rectangular prism.
A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
In other words A= 2(12*10) + 2(10*20) + 2(20*12)
Simplify from there.
A= 2(120) + 2(200) + 2(240)
A= 240 + 400 + 480
A= 1,220

12 I think because its half 24 and 3 x4 =12
