Answer:
V =936 m^3
Step-by-step explanation:
The volume of a cube is given by
V = l*w*h
V = 13*8*9
V =936 m^3
Answer:
its both positive or negative 2
Step-by-step explanation:
Y=x^(2)+2
*subtract the 2 on both sides: 6=x^(2)+2
*square root both sides: 4=x^2
the square root of 4 is 2, so the answer would be positive 2.
we also know -2^2 is positive 4, which gives us
x=+2
x=-2
Answer:
5 x 2 inside the parenthesis
Step-by-step explanation:
We need an order of operations to ensure we always arrive at the correct answer. It gives us a consistent way to work with numbers. We use the mnemonic device like PEMDAS to remember the correct order.
P-parenthesis
E-exponents
M-multiplication
D-division
A-add
S-subtract.
We apply them left to right doing inner operations before outer operations.
There fore our first step is in the parenthesis and multiplication because it is the inner most operations. 5 x 2 inside the parenthesis.
-30-5x=-4x-6(5+4x)
First, you need to use the distributive property on the right to get -30-5x=-4x-30-24x
Then, you can add like terms to get -30-5x=-30-28x
Then, you can add 30 to both sides and add 5x to both sides to get 0=-23x
Finally, you divide both sides by -23 to get 0=x
