Answer:
Step-by-step explanation:
find the area of every face and the base
area of face 1= 2
area of face 2= 2
area of face 3 = 2
area of base 1= 1.7
7.7 in squared
area of a triangle is the base x height divided by 2
face 1- 2 x 2=4
4/2=2
2x3(theres 3 faces to a triangle) =6
area of base- 2 x 1.7= 3.4
3.2/2=1.7
add the faces and the base together
7.7
Answer:

Step-by-step explanation:
The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.

Now solve using inverse operations,

Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).

Substitute,

Solve,

Thus, the answer to this system of equations is the following,
.
Answer:
d = 13 (distance between two points)
Step-by-step explanation:
(4, -2) and (-1, 10)
(X1, Y1) and (X2, y2)
distance between two points = d = sqrt (X2 - X1)² + (Y2 - Y1)²
d = √ (-1 - 4)² + (10 - (-2))²
d = √25 + 144
d = √169
d = 13 (distance between two points)
The x-intercept of a graph refers to the points where the graph cuts or intersects the x-axis.
These are the x-values when y is equal to zero.
From the graph provided, the values of x when the graph cuts the x-axis are:

Therefore, the coordinates of the x-intercepts are:

The answer type is "Two points".
