Seven and five because seven times five is thirty five and seven minus five is two
First we can find the perimeter of the given rectangle
P=2L+2W (L=length and W=width)
P=2*3+2*4
P=6+8
P=14
So now we want to come up with a different combination of numbers that would give up a perimeter of 14. We know that 14 is divisible by 2 so let's make out width 2. If we plug in 2 as the width and 14 as the perimeters, we can solve for length
14=2L+2*2
14=2L+4
10=2L (subtract 4 from both sides)
L=5
So the dimensions are 5 units and 2 units
Hope this helps!
Answer:
30
Step-by-step explanation:
0.5 * unknown number = 15
but
we see unknown number = 15 / 0.5 = 30
Answer: 70, 420, 170
Step-by-step explanation:
x+6x+x+100 = 660
8x+100=660
8x=660-100
x=560/8=70
It's A. 1 1/4 because it show a square and 1/4 of another square
