The sum of the equation is A = x² + x + 1
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the sum of the equations be represented as A
Now , the value of A is
Let the first equation be P
The value of P = 3x² + 4x - 1
Let the second equation be Q
The value of Q = -2x² - 3x + 2
Now , the value of A = P + Q
Substituting the values in the equation , we get
A = ( 3x² + 4x - 1 ) + ( -2x² - 3x + 2 )
On simplifying the equation , we get
A = ( 3x² - 2x² ) + ( 4x - 3x ) + ( 2 - 1 )
A = x² + x + 1
Therefore , the value of A is x² + x + 1
Hence , the equation is A = x² + x + 1

43. If L is the midpoint of KN and MP, which
method can be used to prove the triangles are
congruent?
M
K
A. Side-Side-Side
B. Side-Angle-Side
C. Angle-Side-Angle
D. Angle-Angle-Side
Answer:
Side-Angle-Side
Step-by-step explanation:
See attachment for figures
Given
Midpoint L
Lines KN and MP
Required
Which method proves the congruency of the triangles
Since L is the midpoint, then the following relationship exists:
KL = NLML = PLThis implies that two sides of both triangles are equal
Also, because KN is a transversal of MP and vice versa, then angles KLM and PLN are equal
Conclusively, 2 corresponding sides and 1 corresponding angle have been proven to be equal.
Hence, the method that prove that the triangles are equal is Side-Angle-Side (SAS)

Answer:
-2/4
Step-by-step explanation:
using the rise over run method, you can count how many units up you have to go to get from one point and how many units over. To go from one point on the graph to another, you have to go up 2 units and left 4 units. It is a negative slope since you have to go to the left.

Complete the table below for the equation y = x^2 + 2x - 1. Then, graph the equation on the provided graph grid.
Answer:
y = x^2 + 2x - 1
x = -4
y = -4^2 + 2(-4) - 1
y = 16 + (-8) - 1
y = 7
x = -3
y = -3^2 + 2(-3) - 1
y= 9 + (-6) - 1
y = 2
x = -2
y = -2^2 + 2(-2) - 1
y = 4 + (-4) - 1
y = -1
x = -1
y = -1^2 + 2(-1) - 1
y = 1 + (-2) - 1
y = -2
x = 0
y = 0^2 + 2(0) - 1
y = 0 + 0 - 1
y = -1
x = 1
y = 1^2 + 2(1) -1
y = 1 + 2 -1
y = 2
x = 2
y = 2^2 + 2(2) - 1
y = 4 + 4 - 1
y = 7

The length of the box is 2x - 2 and the width is x - 5. Find the perimeter. (HINT: p= 2L + 2W) Choose one.
A. 2x - 10
B. 6x - 6
C. 6x + 14
D. 6x - 14
Answer:
Option D: 6x-14 is the correct answer.
Step-by-step explanation:
Given that:
Length of the box = L = 2x-2
Width of the box = W = x-5
Perimeter is defined by the sum of length of all sides of the box.
Perimeter of the box = P = 2L + 2W
Perimeter of box = 2(2x-2) + 2(x-5)
Perimeter = 4x-4+2x-10
Perimeter = 6x-14
The perimeter of the box is 6x-14.
Hence,
Option D: 6x-14 is the correct answer.
