Step-by-step explanation:
x²-8x+ 14 =2x+7
x² - 8x +14 - 2x - 7 = 0
x² - 10x + 7 = 0
Answer:
1
4
9
16
25
36
49
64
81
100
Step-by-step explanation:
1 = 1²
4 = 2 x 2 = 2²
9 = 3 x 3 = 3²
16 = 4 x 4 = 4²
25 = 5 x 5 = 5²
36 = 6 x 6 = 6²
49 = 7 x 7 = 7²
64 = 8 x 8 = 8²
81 = 9 x 9 = 9²
100 = 10 x 10 = 10²
Answer:
301.5936 cubic ft
Step-by-step explanation:
Formula for the volume of a cylinder is V = pi*r*r*h, where r represents the radius and h represents the height of the cylinder. Since radius is half the length of diameter, the pipe has a radius of 4/2 = 2 ft.
V = pi*r*r*h = 3.1416*2*2*24 = 301.5936 cubic ft

Answer:
x = 75 m
Step-by-step explanation:
This is a problem of similar triangles solved using proportions.
In similar triangles, corresponding side lengths are proportional.
Here the small and large triangles are similar because the have all three angles congruent.
By proportions, identifying corresponding sides,
x/45 = 50/30
solve for x
x = 45*(50/30) = 75 m
