Answer:
4x^2 -34x+42
Step-by-step explanation:
(4x-6)(x-7)
FOIL
first 4x*x = 4x^2
outer 4x*-7 = -28x
inner : -6 *x = -6x
last : -7*-6 = 42
Add them together = 4x^2 -28x-6x +42
=4x^2 -34x+42
The height of living room ceiling is 15 feet.
Step-by-step explanation:
Given,
Height of ceiling in bedroom = 10 feet
This is 2/3 height of living room ceiling.
Let,
x be the height of living room ceiling.
2/3 of x = 10
Multiplying both sides by 3
Dividing both sides by 2
The height of living room ceiling is 15 feet.

Answer:
L=29ft
W=15ft
Step-by-step explanation:
Step one:
given
let the width be x
W=x
L= x+14
P= 88ft
perimeter= 2L+2W
so, substituting our data we have
88=2(x+14)+2x
88=2x+28+2x
collect like terms
88=4x+28
88-28=4x
60=4x
divide both sides by 4
x=60/4
x=15
Step two:
the dimensions are
the width is 15ft
the length= 15+14
L=29ft
