Answer:

f ( -2 ) = 30

g ( -2 ) = 3

Step-by-step explanation:

when it says f(x) and then has f(-2) - you fill in all x's in the equation with -2.. like this:

f(x) = -7(-2-2) +2                         g(x) = 2(-2)^2 -5

f(x) = -7(-4) +2                             g(x) = 2(4) -5

f(x) = 28 + 2                                g(x) = 8 - 5

f(x) = 30                                      g(x) = 3

hope this helps!!

Aleks04 [339]

Answer:

Colonel Mustard would need to use 2 cubes of wax

pls give brainlyist

Step-by-step explanation:

first solve for area of cone

V = 1/3(BH)

1/3(18.84955592 * 11)

69.11503837cm^3

then solve for the cubes

B*H*W

4*4*4

64cm^3

divide the cone volume by the cubes volume and round up to the largest  hole number

1.07992247

round up

⚠️ PLEASE HELPPPPP<br> find the value of x.
marshall27 [118]
The answer is x=21.

since the equations are both on one side, the sum of the equations will be 180.

5x-17+2x+50=180
add the like variables.
7x+33=180
subtract 33 from 180.
7x=147
divide 147 by 7.
x=21
*to check your answer sub in 21 where the x is and the two answers together and you should get 180*
hope this helps!!

If V is the circumcenter of triangle PQR, find the length of PV.
Sergio039 [100]

9514 1404 393

Answer:

  22.8

Step-by-step explanation:

The circumcenter is equidistant from all the vertices of the triangle: PV = RV. There are enough dimensions given to let us find RV from the Pythagorean theorem.

  RV² = RS² +SV²

  RV² = 11² +20² = 521

  RV = PV = √521 ≈ 22.8
