Answer:
As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.
Therefore, the expression become
And the area of Megan's room is increased by 0.75 square meters.
Step-by-step explanation:
- Let
be the length of the room
- Let
be the width of the room
So the area of the rectangle will be:
As the statement mentions that the new area of the room is % of the previous area.
So the new area of the room becomes:
As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.
Therefore, the expression become
also
so, the area of Megan's room is increased by 0.75 square meters.
Answer:
122 1/4
Step-by-step explanation:
Hope this helps! :)
(12x12) 12x x12) / (3/2 x3/2)
PEMDAS = parathesis exponents multiplictation division add subtract.
12x12=24
3/2x3/2=9/4
12x2/3=8x12=96
so 24+96=120
9/4 can be like 4x2=8 so i remaing
120+2=122 1/4?
Step-by-step explanation:
<h2>Find slope-intercept structure </h2>- y=
- m=2/3, b=-8/3
- therefore the slope will be 2/3
To find y-intercept
- let x=0
- 2(0)-3y=8
- -3y=8
- y=-3/8
To find x-intercept
- let y=0
- 2x-3(0)=8
- 2x=8
- x=4
