Answer:
27x-3
Step-by-step explanation:
3(5x+7)-6(4-2x)
multiply the first expression
15x+21-6(4-2x)
multiply the second expression
15x+21-24+12x
put like terms together
(15x+12x) - (21-24)
add and subtract
27x-3

Answer:
9.22 meters
Step-by-step explanation:
The formula for a pyramid is (base * height) / 3. Therefore, because it's a square, the base is 16, and thus the height divided by 3 = 3. 3 * 3 = 9, so the height is 9. Now we have a right triangle.
If the base edge = 4, half of the base edge is 2. Applying the Pythagorean Theorem, 2^2 + 9^2 = x^2 so then 4 + 81 = x^2. The square root of 85 is approximately 9.22 meters.
Answer:
(6,-11)
Step-by-step explanation:
Given
Point B' = (4,-8)
And the translation formula (x-2, y+3)
In order to get the coordinates of the point before translation, both given points have to be put equivalent.
So, for x-coordinate
x-2 = 4
x= 4+2
x= 6
And for y-coordinate
y+3 = -8
y = -8-3
y=-11
So the old coordinates of old point were (6,-11) ..
