<u>Answer:</u>

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

We are given the following expression and we are to simplify it:

5 a + 3 b - 7 a + 4 b

Re-arranging this expression by writing the like terms together to get:

5 a - 7 a + 3 b + 4 b

Now simplifying it by adding and subtracting the terms to get:

Answer:

Volume= 216 cubic yards

Surface area: 276 square yards

Step-by-step explanation:

Find volume of rectangular prism:

V= lxwxh

V= 3x18x4

= 216 cubic yards

Find surface area:

SA= 2 x (front/back area) + 2 x (right/left area) and 2 x ( bottom/top area)

Front and Back Area:

A= l x w

A = 18 x 3

= 54 square yards

Right/ left Area:

4 x 3

= 12 square yards

Top/ Bottom Area:

18 x 4

= 72 square yards

54^2+12^2+72^2

= 108+24+144

=276 square yards

Find the value of x need answer quick please I tried to make question worth more but I don’t know how :(
Ivan

In the figure we have three parallel lines cut by two transversals

The theorem stares:

If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.

Applying this theorem we have:

\frac{4}{x} =\frac{6}{5}

To solve for x we cross multiply

6x=20

Dividing both sides by 6 we have:

x=\frac{20}{6} =\frac{10}{3}  =3\frac{1}{3}

The second option x=3\frac{1}{3} is the right answer
