Consider the inequality -5(x+7) is less than -10. Write an inequality representing the solution for x.
finlep [7]

Answer:

x > -8

Step-by-step explanation:

First you distribute the -5 and get

-5x-35 < 10

Then you add 35 to both sides and get

-5x<45

Then dived by NEGATIVE 5 (since it is negative you flip the less than signs to greater than) and get

x> -8

the length of a rectangle is 4 meters less than twice its width. The area of the rectangle is 70. Find the dimensions of the rec
Savatey [412]

Answer:  The width is 7 meters. The length is 10 meters.

Step-by-step explanation:   Area = Length × width

Length is 2w - 4  

Substitute that value for length, then solve for w.

70 = w(2w - 4)

70 = 2w² - 4w  reorganize to quadratic equation form

2w² - 4w -70 = 0   These are All even numbers; factor out 2 (divide all by 2)

w² - 2w - 35 = 0  factor this

(w - 7)(w + 5)    set each factor = 0 and calculate the value of w.

w+5=0  w= -5  (disregard this one because dimensions of real rectangles can't be negative)

w - 7 = 0  w = 7   <u>The width is 7</u>

Substitute into the original expressions to get the value of Length.

2(7) -4 = L    14 - 4 = L  The<u> Length is 10.</u>

Check by substituting into the original equation:

w × 2w -4 = 70

7 × 2(7) -4 = 70

7 × 10 = 70    TRUE!

w
