combine like terms :-
(4p+2p+-3p)
(4p+2p+-3p) = 3p
= 3p
B ) 9s- 5s + 2s-S
combine like terms :-
( 9s-5s+2s+-s)
( 9s-5s+2s+-s) = 5s
C ) 8t + 3r - 76 - 9r
combine like terms :-
(3r+-9r)+(8t)+(-76)
= - 6r+8t+-76
How does labeling the diagram help us show that we can use right triangle congruency (SAS in this case)?
Answer:
Step-by-step explanation:
S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.
If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle) the hypotenuse of the two triangles will be congruent.
Now, as hypotenuse and one leg are congruent in both triangles, we can apply RHS congruent

Find the length of the third side. If necessary, round to the nearest tenth. 5 9
Answer: so you have a picture of the shape or what thing we have to find the length to
Step-by-step explanation
The length of the third side is 9.4.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
Applying Pythagorean theorem.
Third side = x
x² = 8² + 5²
8 x 8 = 64 and 5 x 5 = 25
So,
x² = 64 + 25
x² = 89
x = √89
x = 9.433
Rounding to the nearest tenth.
x = 9.4
Thus,
The length of the third side is 9.4.

which equation best represents circle a
Answer:
(x+2)^2+(y-1)^2=3
Step-by-step explanation:
Graph and see which one matches
The equation best represents circle is (x-2)^2 + (y-1)^2 = 12^2, the correct option is B
What is the equation of the circle with radius r units, centered at (x,y) ?If a circle O has radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane, then, its equation is given as:
(x-h)^2 + (y-k)^2 = r^2
Given;
The graph of circle
Now,
h=-2
k=-1
(x-h)^2 + (y-k)^2 = r^2
Substituting the values
(x-2)^2 + (y-1)^2 = 12^2
Therefore, the equation of circle will be (x-2)^2 + (y-1)^2 = 12^2.

Answer:
9
Step-by-step explanation:
use the formula m = y2- y1 / x2 - x1
Answer:
Step-by-step explanation:
The slope of a line can be found using any two points of a line and the slope, m, is defined as
m=(y2-y1)/(x2-x1), we have points (-1,-3) and (0,6) so
m=(6-(-3))/(0-(-1))

The equation 201.50=f+6.50(21) represents the cost of printing the shirts at a second printing company. Find the solution to the equation. The solution is . State what the solution represents in this situation.
Answer:
f = 65
Setup cost = 65
Step-by-step explanation:
Given the equation : 201.50=f+6.50(21)
Solving for f:
201.50 = f + 136.50
201.50 - 136.50 = f
f = 65
The equation above is written in the form a slope intercept function where,, 6.50 is the gradient and X equals the number of shirts, The total cost of printing is 201.50
f is the intercept and represents the initial fee or setup cost. Hence, the setup. Cost = 65
