(2 + x)(3 - x)
To factorise a quadratic we first need to think of factors of the number term (The 6).
Factors of 6 are 1 & 6 and 2 & 3.
What combination of addition or subtraction of these factor pairs will produce the second number (which is positive 1x)
3 minus 2 will give us 1, so we will use this pair
Throw up your brackets with the x's and the number pair we chose
(x 2) (x 3)
We chose 3 minus 2
So in our brackets we will put positive 3, negative 2
(x - 2) (x + 3)

they are both correct due to the commutative property
Solve the formula c = 5p + 215 for p
Answer:
1/5c -43 =p
Step-by-step explanation:
c = 5p + 215
Subtract 215 from each side
c-215 = 5p +215-215
c-215 = 5p
Divide each side by 5
c/5 -215/5 = 5p/5
1/5c -43 =p

Step-by-step explanation:
We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.
Answer:
no solution
Step-by-step explanation:
[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2
[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )
[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )
0 = 4 ← False statement
This indicates the equation has no solution
The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.
Answer:
16x^2 - 8x + 1
Step-by-step explanation:
1. The area of a square can be represented as s^2 or (s)(s), where s = side.
2. (Solving)
Step 1: Set up expression
[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]Step 2: Apply the FOIL method (first, outside, inside, last)
[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]Step 3: Simplify.
[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.

The diagram shows a trapezium PQRS.
Calculate the area of the trapezium PQRS.
Answer:
AREA = 35cmStep-by-step explanation:
Formula in finding the trapezoid's area:
USE THIS FORMULA!: 1/2 × altitude × (base [tex]_{1}[/tex] + base [tex]_{2}[/tex])(note: altitude is also known as the height)
Area = 1/2 × 5 × (6 + 8)
A = 1/2 × 5 × 14
A = 2.5 × 14
A = 35

The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.
Solution:The perimeter of an equilateral triangle is 9n - 12.We know, perimeter of a triangle is the sum of the three sides of the triangle.Also, in an equilateral triangle, all the sides are equal.Therefore, the length of each side of the triangle
[tex] = \frac{9n-12}{3} \\ = \frac{3(3n - 4)}{3} \\ = 3n - 4[/tex]

6. Tell whether the lines are parallel, perpendicular, or neither. *
Line 1: (-3,-1) and (-7,-2)
Line 2: (2.-1) and (8,4)
Parallel with a slope of 1/4
Parallel with a slope of 5/6
Perpendicular with a slope of 1/4 and
Perpendicular with a slope of 1/4
Neither, slopes are 1/4 and 5/6
O
Neither, slopes are 3/10 and 1/2
Answer:
Neither, slopes are 1/4 and 5/6
Step-by-step explanation:
Let's find the slope for Line 1: (-3,-1) and (-7,-2)
m1 = (-2+1)/ (-7+3)
= -1/-4
=1/4
Line 2: (2.-1) and (8,4)
m2= (-4+1)/ (8-2)
= -3/6
= - 1/2
These slope values are not the same, so the lines are not parallel. The slope values are also not negative reciprocals, so the lines are not perpendicular. Then the answer is
Neither, slopes are 1/4 and 5/6

Answer:
Reflexive property
Step-by-step explanation:
The reflexive property of congruence states that any geometric shape is congruent to itself.
Answer:
C) Symmetric Property
Step-by-step explanation:
The Symmetric Property states that If A is congruent to B, then B is also congruent to A. This implies that the congruence is symmetric.
Khan Academy also states that:
When a relation has a symmetric property, it means that the if relation is true between two things, it is true in either order. If VW ≅ XY, then XY ≅ VW.
Therefore, the correct answer is C) Symmetric Property.
