Answer:
Width = 26 inches
Step-by-step explanation:
The area of the rectangle is:
area = (length*width)
416 = a*b
a = b/2 + 3
a = length
b = width
then:
416 = (b/2 + 3) (b)
416 = b*b/2 + b*3
416 = b²/2 + 3b
0 = b²/2 + 3b - 416
b = {-(+3)±√((3²)-(4*1/2*-416))} / (2*1/2)
b = {-3±√(9+832)} / 1
b = {-3±√841}
b = -3±29
only take the positive value becuse is a natural number
b = -3+29
b = 26 inches
a = b/2 + 3
a = 26/2 + 3
a = 13 + 3
a = 16 inches
Check:
416 = 16 * 26
Answer:
x=-10
Step-by-step explanation:
(3x+2)/4=-7
3x+2=4×-7
3x=-28-2
3x=-30
x=-10
Answer:
see below
Step-by-step explanation:
2.5 = 2 5/10 = 250%
40% = .40 = 40/100 = 4/10 =2/5
220% = 220/100 = 2 20/100 = 2 2/10 = 2 1/5
1/4 = 25/100 = 25%
4% = 4/100 = .04
The answer is C. They are intersecting
