Answer:
a² + 2ab + b²
Step-by-step explanation:
(a + b)² = (a + b)(a + b)
multiply each term in the second factor by each term in the first factor
=a(a + b) + b(a + b) ← distribute both parenthesis
= a² + ab + ab + b² ← collect like terms
= a² + 2ab + b²
Answer:
Point N will be located between 0 and -1.
Step-by-step explanation:
Points A and D are placed at (-4, 0) and (4, 0) on a number line.
We have to find the location of a point N which divides AD in the ratio of 3 : 4.
Coordinates of a point (x, y) which divides a segment with extreme ends at and in the ratio of m : n is given by,
x =
y =
By this formula, coordinates of the point N will be,
x =
x =
y = 0
Therefore, coordinates of the point N are .
Point N will be located between 0 and -1.
Here it is. I wrote it down on paper since it is faster to write down the answer then to type on my iPad.
1 1/8 = 1.125
2 2/8 = 2.25
1.125 +2.25 = 3.375 yards total
n = 3.375 x 4.30
n = 14.5125 rounds to $14.51 total
Answer:
11.6 cents per hour.
Step-by-step explanation:
To find the rate per hour we divide the money paid by the number of hours: $82.50/712 = $0.116 per hour or 11.6 cents per hour.
