Please solve this problem I will mark you brainleist ​

Answer 1

Answer:

p(x)= 5(1)^2-3(1)+7=5-3+7=2+7=9

p(t)=4(-2)^4+5(-2)^3-(-2)^2+6=64-40+8+6=24+14=38

Answer 2

Step-by-step explanation:

1. 5x^2 -3x +7

Substituting the value of x

= 5×(1^3) -3(1) +7

= 5 - 3 + 7

= 9

2. 4t^4 +5t^3 -t^2 + 6

Substituting the value of t

= 4(-2^4) + 5(-2^3) -(-2^2) +6

= 4(16) +5(-8) -(4) +6

= 64 -40 -4 +6

= 70-44

= 26
