i need help with algebra 2?

1) ( 2^2 (3^2 +4^2) ) /10^2
=(4 (9+16) )/100
=4.25/100
=100/100
=1
2) (-3). (-u) . (-7v) +8v-6uv
= -21uv +8v-6uv
=8v-27uv
=v(8-27u)

3) -3(p-5) -7p +2(p-18) -6
= -3p +15 -7p +2p -36 -6
= -8p -27
4)2x^2+x-2 for x=3 ,y=2 & z=5
2x^2+x-2
=2.(3)^2 +3 -2
=2.9 +1
=18+1
=19

1)
[2^2(3^2 + 4^2)]/10^2
= [4(9 + 16)]/100
= [4(25)]/100
= 100/100
= 1

2)
(-9)^2(-2 + 2)(-5)
= (81)(0)(-5)
= 0

3)
-3(p - 5) - 7p + 2(p - 18) - 6
= -3*p + 3*5 - 7p + 2*p - 2*18 - 6
= -3p + 15 - 7p + 2p - 36 - 6
= -3p - 7p + 2p + 15 - 36 - 6
= -8p - 27

8)
2x^2 + x - 2
= 2(3^2) + 3 - 2
= 2(9) + 3 - 2
= 18 + 3 - 2
= 21 - 2
= 19

(2^2 ( 3^2 + 4^2 )) / 10^2 = 4(9+16)/100 = 4*25/100 = 1

-3 · -u · -7v + 8v - 6uv = -21uv+8v-6uv = 8v-27uv = v(8-27u)

(-9)^2(-2 + 2)(-5) = 0 (anything multiplied by zero is zero)

3(p-5) - 7p + 2(p-18) - 6 = 3p-15-7p+2p-36-6 =-2p-57

2x^2 + x - 2 = 18+3-2 = 19 for x = 3. Cannot evaluate for y or z as they are not in the expression

1. (4(9+16))/100
(4 x 25) / 100
100/100= 1

2. -3 x -u x -7v + 8v - 6uv
3u(-56v) - 6uv
-168uv - 6uv
-174uv

3. 81 (0) (-5)
= 0

4. -3p + 15 - 7p + 2p - 36 -6
-10p -27

5. I don't know why you would need y or z, but if x=3, then
2(3)^2 + 3 - 2 = 2(9) + 3 - 2 = 18 +3 - 2 =19

(2^2 ( 3^2 + 4^2 )) / 10^2
