What is the solution of

marta [7]

Answer:

$x$

Step-by-step explanation:

Firstly, we know that the solution cannot contain $\leq or \geq$ as when x=3, the equation is undefined. This cuts the options in half

When we plug in a value that is less than 3, we always get a value less than 1. This means that when added to 3, we will always get a value less than 4.

The dimension of a mural pointed on the wall of a school is 10 ft by 22 ft. the art club wants to paint a new mural that is x fe

Westkost [7]

Answer:

18 ft and 30 ft

Step-by-step explanation:

The new dimensions will be:

10 + x and 22 + x

The area is 540

Using area equation we get:

(10 + x)(22 + x) = 540
x² + 32x + 220 = 540
x² + 32x = 320
x² + 2x*16 + 256 = 320 + 256
(x + 16)² = 576
x + 16 = √576 (Ignoring the negative root as the length is never negative)
x + 16 = 24
x = 8

The new dimensions are:

10 + 8 = 18 ft and
22 + 8 = 30 ft
