Compute the following expressions for given values of the variables.
(x^2 + 3y) (3y + 7) for x = 1, y=1​

Answer 1

Step-by-step explanation:

$(1 {}^{2} + 3 \times 1)(3 \times 1 + 7)$

$(1 + 3)(3 + 7)$

$4 \times 10 = 40$

Answer 2

Answer:

(x²+3y)(3y+7)

Step-by-step explanation:

(1²+3×1)(3×1+7)

(1+3)(3+7)

(4) × (10)

= 40
