Answer 1

A.

$(6x + 10y) \times (x + 10)$

$(16xy) \times (10x)$

$160 {x}^{2} y$

B.

$(3a + 4b) \times (a - 2b)$

$(7ab)( - 2ab)$

$- 14 {a}^{2} {b}^{2}$

C.

$(9p {}^{2} - 4q {}^{2} ) \times ( - 2 {q}^{2} + 5q)$

$(5 {p}^{2} {q}^{2} ) \times ( - 7 {q}^{3} )$

$- 35 {p}^{2} {q}^{5}$

D.

$(3a + 2y - 5) \times (a + 9)$

$3a(a + 9) + 2y(a + 9) - 5(a + 9)$

$(3 {a}^{2} + 27) + (2ay + 18) - (5a + 45)$

$(30 {a}^{2} ) + (20ay) - (50a)$

$(30 {a}^{2} + 20ay) - 50a$

$50 {a}^{3} y - 50a$

${a}^{2} y$

D.

Answer 2

hi this is the answer for no A & B

Step-by-step explanation:

number A. soln (6x+10y)×(x+10)

6x(x+10)+10y(x+10)

6x+60x+10xy+100

number B. soln (3a+4b)×(a-2b)

=. 3a(a-2b)+4b(a-2b)

3a²+6ab+4ab-8b²

3a²-2ab-8b²
