5+2(x-5)
you need to follow pemdas. and multiply the 2 with x and -5
5+2x-10
now simplify
-5+2x
finally answer is 2x-5
Answer:
60
Step-by-step explanation:
The perimeter is 30
We scale each length by 2
The new perimeter is 30*2 =60
Step-by-step explanation:
A= l × w
A= (3x+6)×(4x+2)
A= 12x²+6x+24x+12
A=12x²+30x+12
P=2l+2w
P=2(3x+6)+2(4x+2)
P=6x+12+8x+4
P=14x+16
What do you mean by that?
For the first rectangle:
- Find the distance between (-4, 3) & (-2, 6) and (2, -1) & (-4, 3)
- Multiply the distances to get the area of the rectangle.
For the second rectangle:
- Find the distance between (-4, 4) & (-1, -5) and (2, -4) & (-4, 4)
- Multiply the distances to get the area of the rectangle.
Compare areas to see which one is larger.
