Answer:
(x + 8) (x-8)
Step-by-step explanation:
x^2-64
Solve
a^2 - b^2 = (a+b) (a-b)
Where a = x , b = 8
(x + 8) (x-8)
Answer:
Horse A will have traveled 20 feet farther
Step-by-step explanation:
Horse A has traveled 160 feet in 5 seconds, and Horse B has traveled 140 feet in 5 seconds, and 160-140=20
Answer:
The end of the stencil is located at (8, -1)
Step-by-step explanation:
The given parameters are;
Location of the beginning of the left edge of the stencil = (-1, 2)
Location of the detail = (2, 1)
Ratio of detail distance from beginning to detail to distance from beginning to stencil end = 1:2
Distance from beginning to detail = √((-1 - 2)² + (2 - 1)²) = √10
Given that the ratio of the length of the detail to the length of the end after the detail is 1:2 therefore;
√10:Length of stencil side = 1:2
Distance from detail to stencil end = 2×√10
Which gives;
Slope of line = tan⁺¹((2 - 1)/(-1 - 2)) = tan⁺¹(-1/3) = -18.435°
x-coordinates of the end of the stencil = 2√10 × cos(-18.435°) + 2 = 8
y coordinates of the end of the stencil = 2√10 × sin(-18.435°) + 1 = -1
The coordinates of the end of the stencil = (8, -1)
Answer: 80
Step-by-step explanation:
50+50=100
180-100=80
Answer:
D. About $10
Step-by-step explanation:
To find unit price, you divide the total price by how much you're buying.
For example - $56 divided by 6.2 pounds of pecans is 9.032258064516129032258064516129 which can be rounded up to about $10
