Answer:

24m3−168m2+225m+30

Step-by-step explanation:

(3m+−6)(8m2+−40m+−5)

=(3m)(8m2)+(3m)(−40m)+(3m)(−5)+(−6)(8m2)+(−6)(−40m)+(−6)(−5)

=24m3−120m2−15m−48m2+240m+30

=24m3−168m2+225m+30

Explain why a trapezoid is a quadrilateral but a quadrilateral is not always a trapezoid.
Triss [41]
A trapezoid is a quadrilateral because it has 4 sides. A quadrilateral is not always a trapezoid because a quadrilateral can be any shape as long as it has four sides.

I may not make sense but I hoped this helped! :)

I don’t know if it’s A or B
lara31 [8.8K]

Answer:

A

Step-by-step explanation:

this is true due to the ratio of a 30-60-90 triangle, which is 1-2-sqrt(3). The 12 corresponds to the sqrt(3), which means that the 1 corresponds to 4sqrt3 and the 2 to 8sqrt3.

Help me the answer choices are <br> A 2 bags <br> B 3 bags<br> C. 4 bags<br> D.5 bags
SIZIF [17.4K]

Answer:

B. Three bags

Step-by-step explanation:

For this problem you want to first find the area of the triangle so let's use the formula: 1/2*b*h. We can see in the picture that your base is 20m and your height is 6m so let's plug in your values to the equation and you'll get 1/2*6*20. Let's then multiply and we'll get 60.

The problem then states that one bag of topsoil is 20 square meters while our area of the triangle is 60sq. meters. Divide, 60/20=3 therefore you will need 3 bags of top soil for the entire triangular flower bed.

Solve the following equation then place the correct number in the box provided 7x/15 - 1 = 22
iragen [17]

Answer:

x = 345/7

Step-by-step explanation:

7x/15 - 1 = 22

Add 1 to each side

7x/15 - 1 +1= 22+1

7x/15  = 23

Multiply each side by 15/7 to isolate x

15/7 * 7/15 x = 23 *15/7

x = 345/7
