1/2:3/4
1/2 x 6 = 3
3/4 x 6 = 5
therefore, the ratio 1/2:3/4 is equivalent to 3:5 (3.3:4.6 to be exact but i rounded)

Theres are really good video on this
In this problem, two binomials are being multiplied.
First, you see the First terms multiplied together, x^2 and -5x^2.
Then you see the Outside terms multiplied together, x^2 and x.
Next, you see the Inside terms multiplied together, -2 and -5x^2.
Finally, the Last terms are multiplied together, -2 and x.
Put together the bold letters above and you spell FOIL.
FOIL is a way to remember how to multiply two binomials.
F - multiply the First terms.
O - multiply the Outside terms.
I - multiply the Inside terms.
L - multiply the Last terms.
In general, to multiply to binomials
(a + b)(c + d) =
F: ac
O: ad
I: bc
L: bd
= ac + ad + bc + bd
Answer: Choice A. FOIL
Answer:
x=3
Step-by-step explanation:
3x-6x+7=-2
subtract 7 from both sides
3x-6x=-9
-3x=-9
3x=9
x=3
