Answer:

C)   (2, -5).

Step-by-step explanation:

Convert to vertex form:

3x^2 - 12x + 7

= 3(x^2 - 4x) + 7

Completing the square:

= 3[ (x - 2)^2 - 4)] + 7

= 3(x - 2)^2 - 12 + 7

= 3(x - 2)^2 - 5.

Comparing with the general form

a(x - b)^2 + c  we see that the vertex is (b, c)  =   (2, -5).

[NEED THIS ANSWERED QUICKLY]<br> What is the surface area of the triangular prism?
pochemuha

<u>Given</u>:

The base of the triangle is b = 3 feet.

The height of the triangle is h = 4 feet.

The other side of the triangle is 5 feet.

The height of the triangular prism is 20 feet.

We need to determine the surface area of the triangular prism.

<u>Surface area of the triangular prism:</u>

The surface area of the triangular prism is given by the formula,

SA=bh+(s_1+s_2+s_3)H

where b is the base of the triangle,

h is the height of the triangle,

s₁ , s₂ and s₃ are the sides of the triangle and

H is the height of the triangular prism.

Substituting the values, we get;

SA=(3)(4)+(3+4+5)(20)

SA=12+(12)(20)

SA=12+240

SA=252 \ ft^2

Thus, the surface area of the triangular prism is 252 ft²

-12 is greater than or equal to 24x solve
geniusboy [140]
Well this depends a lot about what your variable represents in this problem since if you have like -12 is greater than 24(-5). So it really just depends on your variable but if it's just -12 and 24 then 24 is greater than -12. So -12 is less than 24.
