I believe it would be D. If d=7 then the equation would be 2x7 which would equal 14
X^2 + x + 3x - 3
x^2 + 4x - 3
Therefore the coefficient of x in expansion is 4.
100 cm = 1 m, so the conversion factor must be either 100 cm/1 m or 1 m/100 cm. Since you want to end up with cm, you need cm in the numerator. Then the m in the denominator will cancel out the given m. The answer is B.
Answer:
The width of the rectangle is 5 inches.
Step-by-step explanation:
Perimeter of a rectangle: 2L+2W where L=length and W=width
P=56
56=2(4W+3)+2W
56=8W+6+2W
56=8W+2W+6
56=10W+6
56-6=10W
50=10W
W=50/10=5
W=5
L=4W+3=4(5)+3=20+3=23
