Answer:
37 sq. ft.
Step-by-step explanation:
Multiply 1.5 by 2 and add it to 4 to get the bottom of the triangle part, which is 7. The. Multiply it by 6 and divide by 2 to get the area of the triangle, which is 21. Then find the area of the square part, which is 16, and finally add both areas together to get the total area of the composite figure
Regardless of the sign of
, we have
(never negative). But multiplying by -1 makes it negative.
On the other hand,
which can never be negative for real
.
Answer:
Hi! The formula for surface area is:
area = 2lw + 2lh + 2hw
(l = length, w = width, h = height.)

Answer:
A. (-7 -2)
Step-by-step explanation:
You can eliminate y by multiplying the first equation by 7 and subtracting 6 times the second equation:
7(-3x +6y) -6(5x +7y) = 7(9) -6(-49)
-21x +42y -30x -42y = 63 +294 . . . . eliminate parentheses
-51x = 357 . . . . . . . . collect terms
x = -7 . . . . . . . divide by -51. This matches answer choice A.
