Answer:
-5cd
Step-by-step explanation:
<u>Simplifying:</u>
- -3cd - d(2c - 4) - 4d = ⇒ parenthesis
- -3cd - 2cd + 4d - 4d = ⇒ simplify like terms
- -5cd ⇒ answer
The first choice is correct one.
Solve for m by simplifying both sides of the equation then isolating the variable.
m = -1 + v.
Answer:
216 ft^2
Step-by-step explanation:
area of a triangle: (height * base)/2
in this problem,
height = 12, base = 36
area = 12*36/2 = 6*36 = 216
216 ft^2
Answer60
Step-by-step explanation:
Complement angles mean that the sum of them = 90°
Say one if them = X
then the 2nd will be 5X
X+5X =90°
6X = 90°
X = 90/6
X = 15°
Therefore,
the 1st angle X = 15°
the 2nd angle 5X = 15 ×5 = 75°
