Question

In the blankS.
1.) P (x) = x +4x²+5x-2 then P(1) =​

Answer 1

Step-by-step explanation:

Step-by-step explanation:

Length of the rectangle = 10 cm

Breadth of the rectangle = 8 cm

(i) When they are doubled,

⇢l = 10 × 2 = 20 cm

⇢b = 8 × 2 = 16 cm

Perimeter = 2(l + b)

= 2(20 + 16)

= 2 × 36

= 72 cm

(ii) When they are halved,

⇢l = 10/2 = 5 cm

⇢b = 8/2 = 4 cm

Perimeter = 2(l + b)

= 2(5 + 4)

= 2 × 9

= 18 cm

Answer 2

Answer:

8 is your answer

Step-by-step explanation:

$p(x) = x + {4x}^{2} + 5x - 2 \\ p(1) = (1) + 4({1})^{2} + 5(1) - 2 \\ = 1 + 4(1) + 5 - 2 \\ = 1 + 4 + 5 - 2 \\ = 10 - 2 \\ = 8$
