Answer:

The vertex would be D) (-2, -32)

Step-by-step explanation:

To find the vertex , start by find the x-value. For this we can use the equation below.

x = -b/2a

In which a is the coefficient of x^2 and b is the coefficient of x.

x = -b/2a

x = -(8)/2(2)

x = -8/4

x = -2

Now that we have x, we find y by plugging -2 in for each x.

y = 2x^2 + 8x - 24

y = 2(-2)^2 + 8(-2) - 24

y = 2(4) - 16 - 24

y = 8 - 16 - 24

y = -32

I’m not totally sure about the less and greater signs because I’m not sure you can graph using those signs but either way their are your line equations

Need help finding the side length, thank you! please try and show work or you can

Tasya [4]

Answer: x=16

Step-by-step explanation:

For this problem, we can set a proportion to find the side length of the smaller rectangle.

$\frac{15}{24}=\frac{10}{x}$ [cross multiply]

$15x=240$ [divide both sides by 15]

x=16

Based on the side lengths given (a, b, and c), which triangles are right triangles?

Mekhanik [1.2K]

Answer:

B & C

Step-by-step explanation:

Use the Pythagorean Theorem: a^2 + b^2 = c^2

A) 18^2 + 24^2 = 2,088 | 42^2 = 1,764 [NOT A]

B) 33^2 +56^2 = 4,225 | 65^2 = 4,225 [B IS CORRECT]

C) 19^2 + 180^2 = (32,761) = 181^2 = (32,761) [C IS CORRECT]

D) 3^2 + 4^2 = 25 | 7^2 = 49 [NOT D]

I hope this helped you ! In return, please deem this the most brainliest answer.
