Answer:
x=9
Step-by-step explanation:
The triangle is equilateral which means the sides are equal.
x+9 = 2x
Subtract x from each side
x+9-x = 2x-x
9 =x
Answer:
B. 12.5 feet below the surface of the water
Step-by-step explanation:
-20 + (-32.5) + 40
40 - 52.5
= -12.5 feet
= 12.5 feet below the water
No, because a polygon has to be vertical and a cube is straight.
Answer:
1. y=7.2
2. x=18
Step-by-step explanation:
1. Triangles CMN and CBA are similar triangles (by AAA postulate). Similar triangles have proportional corresponding sides, so
2. GK is angle G bisector. Use angle bisector's property:
Answer:
(goh) (4) = 7
Step-by-step explanation:
(goh) (x) = g(h(x))
Plug in
g(h(x)) = 5(√x) - 3
if x = 4 then
g(h(4)) = 5(√4) - 3
g(h(4)) = 5(2) - 3
g(h(4)) = 10 - 3
g(h(4)) = 7
