The volume of a pyramid would be the base area times the height.
Given the height and volume we can find the base ares by dividing the volume by the height.
64 / 16 = 4
The base area is 4 square feet
Answer:
x = -15
Step-by-step explanation:
7 - 3x = -4(2+x)
7 - 3x = -8 -4x
7 + x = -8
x = -15
I think it’s going to be 4/16 but I’m not a math major and I suck at math so I’m not sure
Steps:
1. Substitute the y in 4x + 10 with -5x-10
-5x-10= 4x + 10
2. Add 5x on both sides
-10= 9x + 10
3. Subtract 10 on both sides
-20= 9x
4. Divide by 9 on both sides
5. Your answer is
X= -20/9
Let X represent the length of the chord.
By using Pythagoras' Theorem:
4^2 + (X/2)^2 = 15^2
(X^2)/4 = 209
X^2 = 836
X = 28.91
