The third one is the answer for this question
Answer:
56x + 34
Step-by-step explanation:
12(3 + 5x) + 1/4(16x - 8)
First, use the distributive property. You will get:
(12)(3) + (12)(5x) + (1/4)(16x) - (1/4)(8)
Next, multiply the numbers. You will then have:
36 + 60x + 4x - 2
Now, rearrange the numbers. The variables go in the front. This is what it should look like:
60x + 4x + 36 - 2
Add 60x and 4x, then subtract 36 and 2. This is your answer:
56x + 34
Answer:
x=12 and the scale factor is 1.5
Step-by-step explanation:
From D' to F' is 7.5 and from D to F is 5cm the difference is 2.5. From F' to E' is x and from F to E is 8. This is just understanding what you can see. You find x by figuring out the ratio from 5 to 7.5 is and 8 to x or vise versa. It depends which way you are going. I think you are going from E,D,F to E',D',F'. So from 5cm to 7.5 cm. This is 1.5 because you are dividing 7.5/5. If you needed to find x, it would be 12.
