Answer:
25
Step-by-step explanation:
You plug in the g(x) function into the f(x) function as the x, after this you replace the x with -1 and solve for you answer, so it should look like
f(g(x))=(2x+7)^2
f(g(-1)=(2*-1+7)^2=25
Answer:
Top row, third one from left to right
Step-by-step explanation:
Use test points:
when x = 0 , y = 2(0) - 4 = 0 - 4 = -4
(0, -4)
when y = 0, 0 = 2x - 4, 4 = 2x, 2 = x
(2, 0)
Top row, third one from left to right
Answer:
(1, 4)
Step-by-step explanation:


Below are a few points for Equations (1) and (2).}

Equation (1) is the blue line in the graph below.
Equation (2) is the red line.
The two lines cross at the black dot
Your four points are labelled . The one that is closest to the intersection is (1, 4).
The approximate solution to the system of equations is (1, 4).
The sides length of the cubical box is 3.8 cm if the volume of a cubical box is 54.872 cm³ option second is correct.
<h3>What is a cube?</h3>
It is defined as three-dimensional geometry that has six square faces and eight vertices.
We have a volume of a cubical box is 54.872 cm³
V = 54.872 cm³
As we know the volume of the cube:
V = side³
54.872 = side³
Taking cube root on both sides:
side = 3.8 cm
Thus, the sides length of the cubical box is 3.8 cm if the volume of a cubical box is 54.872 cm³ option second is correct.

The diagonals of a rectangle are congruent so set them equal to each other to get x = 2x - 7. isolate the variable (0 = x - 7 — x = 7) to get x = 7. the diagonals are seven.
