area = 2x² + 7x - 4
the area (A ) of a rectangle = length × width
A = (2x - 1 )(x + 4 ) ← expand using FOIL
= 2x² + 8x - x - 4 = 2x² + 7x - 4
Answer:
its A
Step-by-step explanation:
Its a because its A =)
Answer:
If solving for y: y = 8 - 2x
If solving for x: x = 
Step-by-step explanation:
<u>To solve for y:</u>
Factor out the common term, which in this case is 3.
3(2x + y) = 24
Divide both sides by 3.
2x + y = 
Simplify
to 8.
2x + y = 8
Subtract 2x from both sides.
y = 8 - 2x
<u>To solve for x: </u>
Factor out the common term, which in this case is 3.
3(2x + y) = 24
Divide both sides by 3.
2x + y = 
Simplify
to 8.
2x + y = 8
Subtract y from both sides.
2x = 8 − y
Divide both sides by 2.
x = 
Answer:
2605
Step-by-step explanation:
2500 + (7000*1.5%)
2500 + 105
2605
Answer:
Step-by-step explanation:
Let the complement = x
Let the angle = 5*x
x + 5x = 90
6x = 90
x = 90/6
x = 15
So the complement = 15
The angle itself is 5*15 = 75
