Answer:
l = 32.5 units, w= 27.5 units, A = 893.75 units²
Step-by-step explanation:
width is w
length is l = 5+w
P = 2( l+w) , substitute l for 5+w
P = 2(5+w+w)
P = 2(5+2w)
P = 10 +4w
P = 120
10 +4w = 120
4w = 120-10
4w = 110
w= 110/4
w= 27.5 units
l = 5+w = 5+ 27.5 = 32.5 units
A = l*w = 27.5 * 32.5 = 893.75 units ²
The answer is at the bottom.
3 times 4/5 = 3/1 times 4/5
so you get 12/5
the question says as the product of a whole number and unit fraction
so it is 2 2/5.
the answer is 2 2/5
Answer:
Total of 9 lengths of 4 inches can be taken out from a board of 3 feet

As
1 ft = 12 inches
So
Length of board in inch = 
= 36 inches
Let no of 4 inches length be = x
The equation become
Total of 9 lengths of 4 inches can be taken out from a board of 3 feet
Answer:
² is the answer i think
Step-by-step explanation:
8-5=3
3-5=-2
