Answer:
`Part A:
D. 3/4(18 + s) = 31.50
Part B:
$36
Step-by-step explanation:
I think 34 is 3/4, is that right?
here, s is the cost of the skirt
Part A: The answer would be:
3/4(18) + 3/4(s) = 31.5 =
3/4(18 + s) = 31.5
Part B: 3/4(18) + 3/4(s) = 31.5
4.5 + 3/4s = 31.5
Subtract 4.5 from both sides:
3/4s = 27, 27 is the cost of the skirt now, but we need the original price.
multiply both sides by 4/3:
s = 36
Answer: The answer is 720
Step-by-step explanation: I started off by guessing a random number, i picked 10. So i multiplied 12x10 and i got 120. I added 120 with 120 until i got something close enough (720.) I got it right on the test as well- :)
The <em><u>correct answers</u></em> are:
B=(xy + x)(xy + x)
; C=(2x – 3)(–3 + 2x)
; and E=(4y² + 25)(25 + 4y²)
Explanation:
In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.
For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).
