A rectangle has a length that is 9 inches less than twice its width. The area of the rectangle is 180 square inches.
a. Write an equation that represents the situation.
b. Find the length and width of the rectangle.
c. Find the perimeter of the rectangle.
pls help lols
Answer:
Step-by-step explanation:
a) Let the width = w
Two times its width = 2*w = 2w
9 inches less than 2w = 2w - 9
Length = 2w - 9
Area of rectangle = length *width = 180 square inches
(2w - 9 ) * w = 180
2w*w - 9*w = 180
2w² - 9w - 180 = 0
b) sum = -9
Product= -360
Factors = -24 , 15 {15 *[-24] = -360 and 15 + (-24) = -9 }
2w² - 9w - 180 = 0
2w² - 24w + 15w - 180 = 0
2w(w - 12w) + 15(w - 12) = 0
(w -12) (2w + 15) = 0
{Ignore 2w + 15 = 0 as measurements cannot be a -ve value}
w - 12 = 0
w = 12 inches
l = 2w -9
= 2*12 - 9
= 24 - 9
l = 15
length = 15 inches
Width = 12 inches
c) Perimeter = 2 *(length + width)
= 2*(15 + 12)
= 2 * 27
= 54 inches

Answer:
x = 10

This is the last one! so please help. The question is in the picture down below !
Answer - Part A:
I would say "whole".
Step-by-step explanation:
So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.
Where, the original price is the total price. So, the means that it is the whole price.
Just to help:
Answer - Part B: The original cost of the jeans are $80.
Step-by-step explanation:
If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.
So, see? 30% of 80 is $24.

Answer:
The only graph whose line is strait
Step-by-step explanation:
This graph represents the situation because energy bills will have a set amount of money which directly correlates with the amount of energy you use. When it gets cold you use more energy to keep you warm. As you use more energy your price rises at the same pace-thus a strait line.

Rounding Whole Numbers/Tenths/Hundredths
help pls
Answer:
so for the first problem, you round to ten since the one place is a nine. for the second one, your round to 67 since the decimal point is 9. for the third one, you round to 100 since it's 94 and anything above 50 rounds to 100. fo the fourth one round to 9 since the decimal point is a 2. for the fifth one you round to 40 since the one's place is a well...1.
Step-by-step explanation:
okay so as we know when the number is over 5 we round up. so for the sixth problem we can see it says we round to nearest whole number meaning the ones place. now when we round we look to the number on the right. in this case its the one on the other side of the decimal point. Which if we see is a 4, which is less than 5 so orund down to 9.
