Answer:

Step-by-step explanation:

1. 6(a +2b +3c)

2. (6 x 1a) + (6 x 2b) + (6 x 3c)

*Note that I put a 1 in front of the a.  I did this because a means there is 1a so by putting the 1 there, it makes it easier to see that 6 x 1= 6, therefore we now have 6a.

3. Answer:

(6a) + (12b) + (18c)

* If you ever have an equation like this that has two of the same letters such as if 12b was 12a, then you could combine those since they are like terms.  But since we have three different letters, this is the most simplified answer.  Hope this helps!!(: If you have any questions just let me know!

What is the area of this trapezoid<br><br> Will mark brainless to right answer and give thanks
aksik [14]

Answer:

80

Step-by-step explanation:

area of trapezoid is given by formula

Area = \frac{a+b}{2}h

where a is one base, b is another base and h is height

In given case, we have

a= 7+7+3 = 17

b= 3

h= 8

Substituting the values

Area= \frac{17+3}{2} x 8

       = \frac{20}{2} x 8

       =  10 x 8

       = 80

Please help me it takes so long to do this please
leonid [27]

Answer:

x = 117°

Step-by-step explanation:

The angle inside the triangle and 101° are adjacent and supplementary, thus

angle inside triangle = 180° - 101° = 79°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle , thus

x = 38° + 79° = 117°

The scale model of a car is 5% of the size of the actual car. The length of
podryga [215]
<h3>Answer:  15 feet</h3>

Explanation:

x = length of the actual car in inches

5% of x = 9 inches

0.05x = 9

x = 9/(0.05)

x = 180 inches

Divide by 12 to convert from inches to feet.

180 inches = (180/12) feet = 15 feet

The area of a circular table is 22511 in2.
zzz [600]

Answer:

1. Radius = 84.65 in

2. Circumference = 531.65 in

3. Diameter = 169.3 in

Step-by-step explanation:

1] In order to find the area of a circle, we use the formula

Area of a circle = πr²

Where r is the radius. So substitute the value of the area of the circle in the formula, to find the radius r.

22511 = π r²

r² = 22511 ÷ π

r = \sqrt{22511 / \pi }

<u>r = 84.65 in</u>

2] Now that we found the radius, we can easily find the circumference using the formula:

Circumference of a circle = 2πr

Substitute the value of r in the formula.

Circumference = 2 × π × 84.65

<u>Circumference = 531.87 in</u>

3] The diameter is twice the radius, so:

diameter = r × 2

diameter = 84.65 × 2

<u>diameter = 169.3 in</u>
