Answer:

A

Step-by-step explanation:

An equivalent expression is an expression which is equal to (x-9)(2x^2-6x+3). You can expand or simplify an expression to make an equivalent expression. Apply the distributive property to form a new equivalent expression by multiplying (x-9) separately into the factor in parenthesis.

(x-9)(2x^2-6x+3)  = x(2x^2-6x+3) - 9(2x^2-6x+3)

find the length of the line segment with end points (7,2) and (-4,2) explain how you arrived at your solution
Inga [223]

Answer:

<h2>11 units</h2>

Step-by-step explanation:

Method 1:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have the points (7, 2) and (-4, 2). Substitute:

d=\sqrt{(2-2)^2+(-4-7)^2}=\sqrt{0^2+(-11)^2}=\sqrt{11^2}=11

Method 2:

Look at the picture. Mark points in the coordinate system.

Read the length of the segment.

In triangles ABC and LMN, ∠A ≅ ∠L, ∠B ≅ ∠M, and ∠C ≅ ∠N. Is this information sufficient to prove triangles ABC and LMN congruent
ipn [44]

Answer:

No

Step-by-step explanation:

No. We have 3 angles of triangle ABC congruent to 3 corresponding angles of triangle LMN. That is AAA. To use ASA, you need two angles and an included side. With three angles, you can prove the triangles similar, but not congruent.

George plays basketball in a week long camp On day 2 he scored 8 points On day 4 he scored 12 points Explain how to measure his
Kay [80]
To measure George's rate of change, we first set out two pairs of independent and dependent data which in this case is the day number and the point

Independent Data: Day 2                          Independent Data: Day 4
Dependent Data: 8 points                         Dependant Data: 12 points

Then we find the difference between the two independent values and the two dependent values

4 - 2 = 2
12 - 8 =4

To find the rate we use the following formula 
the difference of dependent value ÷ the difference of independent value =
4 ÷ 2 = 2

Hence the average rate of change is an increase of 2 points a day
