A = 2lw + 2lh + 2hw
A = 2(12)(3) + 2(12)(5) + 2(5)(3)
A = 72 + 120 + 30
A = 222 cm squared

Hope this helps!! :)

The triangles below are similar find the value of x...help I’m stuck
Sergeu [11.5K]
Well, since it is multiple choice, you can just eliminate the answers. If you take 5/4 it equals 1.25. Then you go through the choices. All of the numbers, except 7.2 (C) are infinite. And, 7.2 gives you the 1.25 from before... which is your answer
If this helped, brainliest would be great! Only need one more to level up :)

Solve the equation 6/5y-10=-4<br> X=
defon

6/5y-10=-4

move -10 to the other side

sign changes from -10 to 10

6/5y-10+10= -4+10

6/5y= 6

Mutiply by 5/6 for both sides

6/5(5/6)y=6(5/6)

Cross out 6/5 and 5/6 , divide by 5 and 6 then becomes y

Cross out 5 and 6 on the right side

x= 5

Answer : x= 5

What is the slope of a line perpendicular to the line whose equation is 3x-7y+14=0?
tatyana61 [14]
1.  Find the slope of the given line.  Do this by solving <span>3x-7y+14=0 for m:

3x + 14 = 7y, which gives us m = 3/7.

2.  Find the slope of a line perpendicular to this one.  It's the negative reciprocal of m = 3/7, or -7/3.
