Solve for a -4+2(3a-5)=(1-1a)

1 answer:

6 0

Distribute the two to each of the values in the parentheses.
-4 +6a-10= 1-1a

Then move like terms to the same side to simplify.
6a+1a=1+10+4
7a=15
a=15/7

Jet001 [13]

Answer:

x=1

Step-by-step explanation:

6-3x=5x-10x+8=

move all terms to the left:

6-3x-(5x-10x+8)=0

add all the numbers together, and all the variables

-3x-(-5x+8)+6=0

get rid of parentheses

-3x+5x-8+6=0

add all the numbers together, and all the variables

2x-2=0

move all terms containing x to the left, all other terms to the right

2x=2

x=2/2

x=1

A rectangle has side lengths 2x + 3 and 5x - 2.

xz_007 [3.2K]

Answer:

10x² + 11x - 6

Step-by-step explanation:

The area (A) is the product of the sides, that is

A = (2x + 3)(5x - 2) ← expand using FOIL

= 10x² - 4x + 15x - 6 ← collect like terms

= 10x² + 11x - 6
