Answer:
The correct options are;
Adding rational expressions
Subtracting rational expressions
Step-by-step explanation:
When adding or subtracting rational numbers, the denominators of the fractions representing the numbers should be equal
Therefore, when adding two or more rational expressions together, the following steps are required;
1) Looking for the Lowest Common Denominator
2) Finding the product of the quotient obtained from dividing the LCD by the denominator of a fraction and the numerator of the fraction
3) Placing the sum (or differences) of the products obtained in the above step as the numerator, while the LCD remain denominator
4) Simplifying the numerator in the above step
5) The faction so obtained, is the sum or difference of two or more rational expressions.
#3 is 1920 cubic inches
#4 i cant see the shape
Explanation:
the height is 1 inch so we can disregard that.
58 squared minus 38 squared is 1920 because if it was a square it would be side length 58 but we have to subtract 20 to find what is missing.
Answer:
The line of symmetry is x = 8
Step-by-step explanation:
To find the line of symmetry in an absolute value function, look to the base formula.
f(x) = alx - hl + k
In this equation, h is the line of symmetry. Therefore, we know it to be 8
Add 5x and -3x
2x+8=-10
Subtract 8 from each side
2x=-18
Divide 2 from each side
X=-9
Hope this helps!
