Hello! The answer has to do with multiplication and 3 * 31 is 93. Adding, subtracting, and dividing will not give you the same answer. 3 * 31 = 31 * 3 demonstrates the communtative property and A is the only one that makes sense. The answer is A: 31 * 3.
A. 4/9 = 12/25
cross multiply
(4)(25) = (9)(12)
100 = 108.....this does not form a proportion
B. 3/7 = 18/42
cross multiply
(3)(42) = (18)(7)
126 = 126......this forms a true proportion <==
C. 5/11 = 20/45
cross multiply
(5)(45) = (11)(20)
225 = 220...this does not form a proportion
D. 5/8 = 15/25
cross multiply
(8)(15) = (5)(25)
120 = 125....this does not form a proportion
Answer:
A and D i think
Step-by-step explanation:
<span><span>The numerator will be, x2</span>+12x+35=(x+7)(x+5)</span>
The denominator would be,<span>3x+15=3(x+5)</span>
so you will have this equation.<span>(x+7)(x+5)/3(x+5)</span>
You can cancel out the (x+5) terms on the bottom and top and you end up with:<span><span>(x+7)/3</span></span>
