The bar between the numerator and denominator of a fraction represent division.
Answer:
Step-by-step explanation:
When we have any quantity being multiplied to an expression, we can use the <em>distributive property</em>. The distributive property says that . In other words, we can <em>distribute</em> the outer number inside the parentheses.
Using the distributive property, we can then simplify the given equation as follows:
Finally, you should recall that when multiplying square roots, you can simply bring all the numbers inside of one root. For instance, <em>(note, this does not work for addition or subtraction, only multiplication or division)</em>. Therefore, we can simplify .
Finally, we can combine our answer into
A. The ratio of cups of sugar to butter is 3/4 : 1/8. Then multiply both ratios by 8.
8 x 3/4 = 6,
8 x 1/8 = 1.
3/4 : 1/8 is equal to 6 : 1. Therefore, 6 cups of sugar needed when there is 1 cup of butter.

Add the five to each side.
then square it to get rid of the square root
2x+13=(5+x)^2
2x+13=x^2+10x+25
2x=x^2+10x+12
x^2+8x+12=0
(x+6)(x+2)
x+6=0
x+2=0
answers are -2 and -6, however, when pluging -6 in it doesnt work, so it is only -2.
