6x^2+14x-12 is the answer
Answer:
12
Step-by-step explanation:
4 pounds is 22 people
8 is 44
12 is 66
You get 20$ dollars. Because if you divide 35 by 7 you get 5 then times 5*4=20
Yes, both of these ratios are proportional. You could either plug it into an equation and solve it, or do like I did and divide. If you divide 16 by 12, you get 0.75. If You divide 24 by 18, you also get 0.75, therefore they are equal. The reason why I divided by the numbers that I did is because you're trying to figure out how much it increased and if it was equivalent. They increased 0.75% of their size that they started with. I hope this helps!
Answer:
x = 18
Step-by-step explanation:
To write a proportion, we need to write down the data we have.
Shorter side of rectangle 1 = 6
Longer side of rectangle 1 = 13
Shorter side of rectangle 2 = x
Longer side of rectangle 2 = 39.
A proportion representing this would be:
Solving this proportion for x, we would have:
Therefore, the shorter side of the second rectangle is 18.
