Answer:
4(2x - 3) is how I would write it algebraically.
Step-by-step explanation:
The number is x, as it is unknown. 2x means you multiply the unknown number by 2.
2x
Now, you subtract 3.
2x - 3
And then you multiply the result of that by 4, hence the parentheses.
4(2x - 3)
To solve, just distribute 4. 4*2x = 8x. 4*-3 = -12.
8x - 12
Answer:
=24in^2
Step-by-step explanation:
Whole perimeter: 72 in
72/3= 24 in
10+7h=24
7h=14
h=2
Area= 1/2 (24)*2
=24in^2
Answer:
the 3rd one
Step-by-step explanation:
earnings * 20 percent = 17
earnings * .2 = 17
divide by .2 on each side
earnings = 17/.2
earnings = $85.00
7 - 5x - (3 + 5x)...distribute thru the parenthesis
7 - 5x - 3 - 5x =
-10x + 4...or 4 - 10x
