Answer:
2(3x+6) = 6x+12
3(2x-6) = 6x-18
6x+12=6x-18
Subtract 12 from 18, which gives you:
6x=6x-6
Subtract the 6x on the opposite side of the equal side, and your answer is: x = -6
Answer:
∠ STR = 64°
Step-by-step explanation:
Since RS = ST then the triangle is isosceles and the base angles are congruent, that is
∠ STR = ∠ SRT , then
∠ STR =
=
= 64°
eight time the difference of a number and 2 is the same as 3 times the sum of the number and 3
8* (n-2) = 3*(n+3)
distribute
8n-16 =3n+9
subtract 3n from each side
5n-16 =9
add 16 to each side
5n = 25
divide by 5
n=5
Using the formula for area for a parallelogram, A=BH, where A is area, B is Base, and H is height, you follow that. So in this case, you would want to find one of the area's then multiply it by 4. So for the area you get 20.52 meters. If you multiply it by 4, you get 82.08 meters. Have a nice day
Answer:
The first one
Step-by-step explanation:
The figure shown is a rectangular pyramid
The volume of a rectangular pyramid can be calculated using the formula

where l = length of base, w = width of base and h = height
We have a given length of 6 in, a given width of 4 in and a given height of 8 in
That being said, we plug in the given values into the formula

This equation matches A therefore A is the answer
