2(5x-7)=2x+10 what Is the distributive property

jek_recluse [69]

Answer:x = 3

Step-by-step explanation:

2(5x-7)=2x+10

distribute 2(5x-7)

=2*5x - 2*7

∨ ∨

10x - 14

10x - 14 = 2x + 10

add 14 to both sides

10x-14=2x+10

+14 +14

simplify

10x=2x+24

subtract 2x to both sides

10x=2x+24

-2x -2x

simplify

8x=24

divide both sides by 8

8x=24

÷8x ÷ 8x

x = 3

The perimeter of a rectangle is 48. the length of the rectangle is four less than three times the width. What is the length of t

UkoKoshka [18]

The length of rectangle is: 17

Further explanation:

Given

Perimeter = 48

Let L be the length

Let W be the width

Then

$2L+2W=48\\AND\\L=3W-4$

Putting the value of L in perimeter

$2(3W-4)+2W=48\\6W-8+2W=48\\8W-8=48\\8W=48+8\\8W=45\\\frac{8W}{8}=\frac{56}{8}\\W=7$

Putting W=7 in second equation

$L=3(7)-4\\L=21-4\\L=17$

Hence,

The length of rectangle is: 17
