Answer:

-2(9x-8)

Step-by-step explanation:

We are to simplify the expression -3.1x+7-7.4x-1.5x-6(x-3/2)

Open the parenthesis

-3.1x+7-7.4x-1.5x-6(x-3/2)

= -3.1x+7-7.4x-1.5x-6x+6(3/2)

= -3.1x+7-7.4x-1.5x-6x+9

Collect like terms

= -3.1x-7.4x-1.5x-6x+7+9

= -12x-6x+16

= -18x+16

= -2(9x-8)

Hence the simplified form of the expression is -2(9x-8)

Find the volume of the rectangular prism: 1\frac{1}{2}\ \textit{inches},\ 2\frac{1}{2}\textit{inches},\ \ 3\ \textit{inches}1 2

loris [4]

Answer:

$\dfrac{45}{4}\ \text{inches}^3\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$

Step-by-step explanation:

Dimensions of prism

$1\dfrac{1}{2}=\dfrac{3}{2}\ \text{inches}$

$2\dfrac{1}{2}=\dfrac{5}{2}\ \text{inches}$

$3\ \text{inches}$

Volume is given by

$V=\dfrac{3}{2}\times \dfrac{5}{2}\times 3=\dfrac{45}{4}\ \text{inches}^3\\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$

The volume of the rectangular prism is $\dfrac{45}{4}\ \text{inches}^3\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$ .
