Answer:

D. HL (hypotenuse leg)

Step-by-step explanation:

There are two triangles in the picture, ABQ and CDP. The condition for the hypotenuse leg are:

1. both triangles are right triangle

2. the hypotenuse and one of the leg/side is equal

Both B and D angle is 90 degrees, so both triangles is right triangle. The hypotenuse for the triangle is AQ and PC, and both are equal. One of the triangles legs also equal, which is AB and CD. With that, you fulfill HL postulate for the congruent triangle.

Don't confuse this with SAS theorem for the same angle should be on the middle of two equal sides.

Answer: b) (x - 2)(x + 1)(x + 3)

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

Look at the graph to find the x-intercepts (where the graph crosses the x-axis).

x = 2 x = -1 and x = -3

Now rearrange each of those equation so they are equal to zero:

x - 2 = 0 x + 1 = 0 and x + 3 = 0

Next, combine them (using multiplication):

(x - 2) (x + 1) (x + 3) = 0

Lastly, evaluate the sign of the a-value (coefficient of the polynomial):

Since the right side of the graph goes to POSITIVE infinity, then the a-value is positive.

Sofia wants to rent an apartment. She visits Apartment A which charges $100 for a one-time deposit and $400 per month for rent.

Dimas [21]

Answer:

It takes 9 or more months for the Apartment B to pay less than Apartment A.

Step-by-step explanation:

Apartment B:

8 x 350 = $2800

$2800 + $500 = $3300

----------------------------------------------

9 x 350 = $3150

$3150 + $500 = $3650

Apartment A:

$400 x 8 = $3200

$3200 + $100 = $3300

----------------------------------------------

9 x 400 = 3600

3600 + 100 = 3700
