Answer:
x = -8
Step-by-step explanation:
Look at the screenshots given below for the step-by-step explanation
To find the surface are of the base: 8 * 8 = 64/2(becasue its a triangle not a square base) = 32.
To find the surface are of the 3 other faces, 12 * 8 = 96/2 = 48 * 3(for the 3 sides) = 144.
The entire surface area is 176.
The answer is -15
x = -15 because 10+5=15 and 15 + -15 = 0
Because when multiplying you add the number of variables, and there are 3 X's so it would be 6x with an exponent of 3
Hello!
First: subtract 4 into 12
1/2x=8
Second: divide 8 by 1/2
x=16 because it takes 16 , 1/2 to get 8.
I hope it helps!
