Question

Can someone help me find the answer to these 3 problems if so thank you .

Answer 1

1. r+s²=49

2. pq²=24

3. -4xy-6x²+2x²y-6y= -54

Step-by-step explanation:

1. r+s²=0+7²=49

2. pq²=(6)(2)²=6(4)=24

3. -4xy-6x²+2x²y-6y= -4(3)(2)-6(3)²+2(3)²(2)-6(2)

= -24-6(9)+2(9)(2)-12

= -24-54+36-12

= -78+36-12

= -42-12

= -54
