It would be (BASE * HEIGHT) = AREA

Answer:
Step-by-step explanation:
area of triangular face = ½·3·4 = 6 cm²
area of 3 by 7 face = 3×7 = 21 cm²
area of 5 by 7 face = 5×7 = 35 cm²
area of 4 by 7 face = 4×7 = 28 cm²
total surface area = 2×6 + 21 + 35 + 28 = 96 cm²
x/6+4= 15
Subtract 4 from both sides; 4s cancel each other out
x/6+4-4= 15-4
x/6= 11
multiply both sides by 6 to eliminate fraction (multiply by reciprocal of 1/6)
(x/6)(6)= (11)(6)
x= 66
ANSWER: x= 66

Answer:
It helps you know if the answer is reasonable because when you do the work and get your answer, you can check if it is close to your estimate, and if it is, it is most likely correct. On the other hand if it is not close to the estimate it is most likely wrong, unless you estimated incorrectly.
Step-by-step explanation:
The y intercept is 2.25 and x intercept is -3
