A rectangular solar panel has a length that is 11 inches shorter than 4 times the width. If the perimeter of the panel is 198 inches, what are the dimensions of the panel

79.2x19.8

Step-by-step explanation:

Length(L)=4xwidth(w) L=4w

Perimeter(p)=198

P=2L+2w 2L+2w=198

Substitute L=4w in 2L+2w=198

2(4w)+2w=198

8w+2w=198

10w=198

w=198/10

w=19.8

Substitute w=19.8 in L=4w

L=4x19.8

L=79.2

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
