Which algebraic expression is equivalent to the expression below? (3x + 12) + 8x a. (3x + 8x) + 12 b. (3x - 8x) + 12 c. 23x d. (3x + 12x) + 8

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
