Tema [17]

Answer:

<h3>a. 3x+15</h3><h3>b. 4x-16</h3><h3>c. 10x+2</h3><h3>D. 7x-63y</h3>

solution,

a. \: 3(x + 5) \\  \:  \:  = 3 \times x + 3  \times 5 \\  \:  \:  = 3x + 15

b. \: 4(x - 4) \\  \:  \:  = 4 \times x - 4 \times 4 \\  \:  \:  = 4x - 16

c. \: 2(5x + 1) \\  \:  = 2 \times 5x + 2 \times 1 \\  \:  \:  = 10x + 2

d . \: 7(x - 9y) \\  \:  = 7 \times x - 7 \times 9y \\  \:  \:  = 7x - 63y
