Answer:
C Cos32
Step-by-step explanation:
Answer:
9.2
Step-by-step explanation:
first i added 5 + 3 = 8
then i did 1 1/5 + 8=9 1/5
X/4 + 12 = 5
to isolate the variable the first step is to subtract 12 from both sides
x/4 + 12 - 12 = 5 - 12
x/4 = -7
next, to get rid of the division by 4, multiply both sides by 4
(x/4)*4 = -7*4
x = -28
Answer:1. 4x^2-3x-6
2. 4x^2+7x-8
3. Is the same problem as #2
Step-by-step explanation:
Answer:
298 cm^2.
Step-by-step explanation:
There are 3 pairs of faces of equal area.
Area of top = 7 * 11. So it's 2 * 7 * 11 = 154.
Area of a smaller side = 7 * 4 so we have 2*28 = 56 .
Area of larger side = 4*11 so it's 2*44 = 88.
Total surface area = 154 + 56 + 88
= 298.
