Answer:
42m2
Step-by-step explanation:
9x4=36m2
3x2x0.5=3m2x2=6m2
36+6=42m2
Answer:
e = 6
Step-by-step explanation:
10e - 2e - 9 = 39
8e - 9 = 39
8e = 48
e = 6
CHECK:
10(6) - 2(6) - 9 = 39
60 - 12 - 9 = 39
39 = 39
Answer:
P = 62° Q = 28°
Step-by-step explanation:
Let x = measure of angle Q
then y = measure of angle P
Now x + y = 90 and 2x + 6 = y
Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.
3x + 6 = 90
3x = 84
x = 28
y = 2(28) + 6 = 56 + 6 = 62
Check: 28 + 62 = 90
