Answer:E and A
Step-by-step explanation:
Two out of four can be represented as:
2/4
OR
1/2
Subtract 2 from both sides and you get 2x>2, dived 2 from both sides to isolate the variable. Then you get x>1 :)
Given are the statements describing the area of the baby quilts:
Inside dimensions = 4 x 5 feet
Border with uniform width = x feet
Total area of the quilt = 30 square feet
A = length x width
Area of inside quilt = 4 x 5
Area of quilt including the border = (4+2x) * (5+2x)
Therefore, the equations that are applicable are:
<span>2: (4+2x)(5+2x)=30
</span><span>4: 4x^2 +18x+20=30</span>
