We can write equations, using x and y as the length and width:
xy=40
2x+2y=26
Divide the second equation by two to get:
xy=40
x+y=13
Thus, x=13-y.
We now have (13-x)x=40, so
and
Factoring, we get:
(x-5)(x-8)=0
So, x can be either 5 or 8 (and y will be the other option). Thus, the length and width are 8 and 5.
Answer:
he needs 55 to cover the one rectangular side of the tent with the rip
one rectangular side=55
If Marcus’s dad wanted to re-cover the whole tent including the bottom, he would need 189.
3 rectangular sides=165
2 triangular sides=24
165+24=189
Step-by-step explanation:
Answer:
The number is 59/5 or 11.8 (decimal)
Step-by-step explanation:
This sentence can be written as 5(x-6)=29
x-6 = 29/5
x = 29/5 + 6
x = 59/5 or x = 11.8
Answer:
35 degrees
Step-by-step explanation:
90 degrees (right angle) - 55 degrees = 35 degrees
Answer:
28
Step-by-step explanation:
Difference means subtraction.
10 - (-18) = 28
2 negatives make a positive.
