Answer:
The surface area is 91
Step-by-step explanation:
3*4=12
12/2=6
6*2=12
7*5=30
4*7=28
3*7=21
12+30+28+21=91

Finito.
the equation describes a horizontal line with a y-intercept of -4. as the line is horizontal, the slope is 0.
Answer:
x=38
Step-by-step explanation:
First, know that the sum of the angles in a triangle is 180.
Then, add the angles. 2x+38+x+x-10.
Make them equal to 180.
2x+38+x+x-10=180
Simplify.
4x+28=180
Subtract 28 from 180.
4x=152
Divide 4 from 152 to make x alone.
x=38
There you go!
