The answer to 26 is 11
The formula to find the area of a circle is A = r 2, or A = 2 x 2 in this case. That would be 12.57, or 13 if we’re rounding to the hundredth.
To find the parallelogram, it’s A = B h / A = 6 x 4 which is 24
You then subtract 13 from 24 to find the shaded region which is 11.
Answer:
n= -6
Step-by-step explanation:
Simplifying
4 + -7n = -1(8n + 4) + 2
Reorder the terms:
4 + -7n = -1(4 + 8n) + 2
4 + -7n = (4 * -1 + 8n * -1) + 2
4 + -7n = (-4 + -8n) + 2
Reorder the terms:
4 + -7n = -4 + 2 + -8n
Combine like terms: -4 + 2 = -2
4 + -7n = -2 + -8n
Solving
4 + -7n = -2 + -8n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '8n' to each side of the equation.
4 + -7n + 8n = -2 + -8n + 8n
Combine like terms: -7n + 8n = 1n
4 + 1n = -2 + -8n + 8n
Combine like terms: -8n + 8n = 0
4 + 1n = -2 + 0
4 + 1n = -2
Add '-4' to each side of the equation.
4 + -4 + 1n = -2 + -4
Combine like terms: 4 + -4 = 0
0 + 1n = -2 + -4
1n = -2 + -4
Combine like terms: -2 + -4 = -6
1n = -6
Divide each side by '1'.
n = -6
Simplifying
n = -6
Answer:
28
Step-by-step explanation:
V = (1/3)Bh
V = (1/3)(7 ft)(2 ft)(6 ft)
V = 28 ft^3
To do this you would have to use the Pythagorean Theorem, which is
a^2+b^2=c^2
The longest side would be your c^2, the smallest side is your a^2, and the remaining side is your b^2
The 7 is your a^2, 24 is b^2, and x is c^2
Plug in the numbers into your equation
7^2+24^2=x^2
Then, just solve:
49+576=x^2
625=x^2
To get rid of the ^2 in x^2, you would have to square root both sides to get x by itself
25=x
So x is equal to 25
