Answer:
y=-4/23
im not sure i didn't check (might be wrong)
Step-by-step explanation:
4x - 5y = -28
-3x - 2y = 10
then make x the same
So
12x-15y=-84
-12x-8y=80
then its left with
-23y=-4
y=-4/23
find x by entering y into -3x - 2y = 10 and solving

Answer:
4,257 m²
Step-by-step explanation:
step 1
Find the lateral area of the rectangular prism (ottoman)
The lateral area is
LA=PH
where
P is the perimeter of the base
H is the height of the prism
Find the perimeter of the base P
P=2(37+21)=116 cm
we have H=30 cm
<em>Find the lateral area</em>
LA=116(30)=3,480 m²
step 2
Find the area of the top of the ottoman
B=37*21=777 m²
step 3
we know that
The fabric needed to cover the sides and top of the ottoman is equal to sum the lateral area plus the area of the top
3,480+777=4,257 m²
