Question

Evaluate 9(4x – 15) if x = 3.

Answer 1

Answer:

-27

Step-by-step explanation:

9(4x – 15)

Substitute 3 for x

9((4)(3) - 15)

Multiply (4)(3) = 12

9 ( 12 - 15 )

Subtract 12 - 15 = -3

9(-3)

Multiply 9(-3) = -27

Answer 2

$\implies {\blue {\boxed {\boxed {\purple {\sf {-27}}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$\: 9 \: (4x - 15)$

Plugging in the value $x = 3$ in the above expression, we have

➼ $\: 9 \: (4 \times 3 - 15)$

➼ $\: 9 \: (12 - 15)$

➼ $\: 9 \: ( - 3)$

➼ $\: - 27$
