Answer:
Hope it helps U can still ask me if u have confusions
Answer:
The Answer is C
Step-by-step explanation:
3x-4y=5
2x+4y=-3
This equation is the answer to this problem because just by looking at it, you can immediately cancel out the y value and solve for x.
The other equations are wrong because their is extra work needed to eliminate the values.
Answer:
900
Step-by-step explanation:
The figure is a triangular prism
The equation would be V = A * H / 3
V being the volume
A being the area of the pyramids base
H being the height front he base to the top (20)
Base area is 135 (A)
135 * 20 = 2700
2700 divided by 3 = 900
900 is your answer

Answer: C) x = 13</h3>
====================================================
Work Shown:
We have a right triangle with legs a = 5 and b = 12. The hypotenuse is c = x which is unknown for now.
Use the pythagorean theorem to find x.
a^2 + b^2 = c^2
5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
x^2 = 169
x = sqrt(169) .... apply the square root to both sides
x = 13
