Simplify 7 - 2(5 - 2x) -10x + 25 -4x - 3
Kisachek [45]

Hi,

Let's simplify this equation step-by-step.

7−2(5−2x)−10x+25−4x−3

Distribute:

=7+(−2)(5)+(−2)(−2x)+−10x+25+−4x+−3

=7+−10+4x+−10x+25+−4x+−3

Combine Like Terms:

=7+−10+4x+−10x+25+−4x+−3

=(4x+−10x+−4x)+(7+−10+25+−3)

=−10x+19

Answer:

=−10x+19

Have a great day!

A rope 13 meters long will just reach from the top of a flagpole to a point on the ground 12 meters from teh base of the flagpol
goldfiish [28.3K]

Answer:

the height of the flagpole is 5 meters

Step-by-step explanation:

The computation of the height of the flagpole is given below

Given that

the length of the rope is 13 meters

And, the ground would be 12 meters

Based on the above information, the height of the flagpole is

= √13^2 - √12^2

= √169 - √144

= √25

= 5 meters

hence the height of the flagpole is 5 meters
