Should be a) difference of squares since 25 and 9 are both perfect squares. A radical will simply that into (5-3) squared, which equals 16.
A ratio is an expression used to compare two quantities. A simplified ratio can be taken as is, but if a ratio has not yet been simplified, you should do so to make the quantities easier to compare and understand. In order to simplify a ratio, you divide both terms (both sides of the ratio) by the same number.
Answer:
Plug into calc
Step-by-step explanation:
A= P(1+r/n)^nt
A= 10000(1+.13/12)^12*3
Step-by-step explanation:
y and x are proportional:
y = kx
When x is 29, y is 275.5.
275.5 = 29k
k = 9.5
y = 9.5x. When y is 408.5:
408.5 = 9.5x
x = 43
A relationship that can be modeled as a line that passes through the origin (y = kx) is a proportional relationship.
