<h3><em><u>Simplify -3y+2x-5y-7x is:</u></em></h3><h3>-8y - 5x</h3>

<em><u>Solution:</u></em>

<em><u>Given that, we have to simplify</u></em>

-3y + 2x-5y-7x

We can simplify the above expression by combining the like terms

Like terms are terms that has same variable ( with same exponent) with same or different coefficient

From given,

-3y + 2x-5y-7x

Here, like terms are -3y and -5y

And 2x and -7x

Group the like terms

-3y-5y+2x-7x

Combine the like terms

-8y -5x

Thus the given expression is simplified

This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find th
NISA [10]

Answer:

The volume of the triangular prism: 59.2 ft^{3}

The value of the concrete used is: 16*4 = $64

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo

My answer:

As we know that, the formula to find out the volume of the triangular prism is:

V = \frac{1}{2} a*b*h when h is the height and a&b are the length of the two square edges. So we have:

  • V = \frac{1}{2}*4*4*7.4 = 59.2 ft^{3}

To find the concrete used in the ramp if the cost of concrete is $ 4.00 per cubic foot, we need to know the area of the ramp, which is:

S = 4*4 = 16 ft^{2}

Hence, the value of the concrete used is: 16*4 = $64

Use the distrubutive property to simply 2(-5-7j)
prisoha [69]

<u>Answer:</u>

2(-5 - 7j) = -10 - 14j

<u>Step-by-step explanation:</u>

Using the distributive property means that we have to multiply both -5 and -7j by 2:

2(-5 - 7j)

⇒ 2 × -5  +  2 × -7j

⇒ -10 - 14j
