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).
Jillian bikes a total of 30 miles in 5 days, then we divide 30 and 5 to get 6. Jillian bikes 6 miles per day.
Answer:
x = 30
Step-by-step explanation:
4x + 2x = 180
6x = 180
x = 30
Answer:
x = 10
Step-by-step explanation:
Assuming you mean (1/4)(4x - 24), we simplify this to obtain:
x - 6 + x = 14
Combining like terms, we get:
2x = 20. Then x = 20/2, or x = 10
