Answer:

5a²

Step-by-step explanation:

It is 5a² because 7a² and 2a² are like terms, so we are able to subtract them. If we subtract 7-2 we get 5. It is the same thing, 7a²-2a² is equal to 5a²

Hope this helps!

Find the midpoint of the line segment whose endpoints are (-2, 5) and (6, -9). (4, -4) (2, -2) (1, -4)
Rus_ich [418]

Answer:

(2,-2)

Step-by-step explanation:

The midpoint of the line segment with endpoints (x_1,y_1) and (x_2,y_2) has coordinates

\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

If the endpoints of the line segment are (-2,5) and (6,-9), then the midpoint has the coordinates

\left(\dfrac{-2+6}{2},\dfrac{5+(-9)}{2}\right)\\ \\\left(\dfrac{4}{2},\dfrac{-4}{2}\right)\\ \\(2,-2)

State if the triangles are similar. If so, how do you know they are similar and complete the similarity statement. Triangle LKJ≈
Llana [10]

Answer: C) similar, SAS similarity, triangle LQR

==============================================

Explanation:

The vertical angles KLJ and QLR are congruent. This forms the "A" in "SAS". The angles in question are between the marked sides.

KL = 18 is twice that of QL = 9, or put another way, KL/QL = 18/9 = 2. The ratio of the sides is 2. Also, JL/RL = 16/8 = 2 is the same ratio. Because both pairs of sides have the same ratio, the sides are in proportion. This helps form the two "S" letters of "SAS".

The original triangle has LKJ mentioned at the top. Note the order as its important. We start with L and move to K, so LK is the first segment mentioned. LK = 18 pairs up with LQ = 9, meaning that LQ must be the first segment mentioned of the answer triangle. Therefore LQR is the correct letter sequence if we start with point L. Writing QLR is not correct because Q is the first letter here but Q does not pair up with L.

What’s the answer? I don’t understand the question
Mice21 [21]

Answer:

Step-by-step explanation:

For 3. Amanda has the closest amount of yellow because 3/4 is the closest number to being whole. If I had 3/4 (Amanda) vs 3/5 (Dena) Amanda would win because she has the closest number to 4 while Dena is close but she’s 2 away from getting a whole and Amanda has 1.

4. 3/5 is the amount that’s yellow. So subtract 3-5 and that would leave you with 2/5 as your answer.

5. No, because technically they’re equivalent/equal to each other. 3-5 = 2 and 6-8 = 2 so they both have the same amount of yellow.
