Answer:
15a^2 -17a +4
5a x 3a = 15a^2 bc a times a makes it squared.
next, 5a x -1 = -5a
and then -4 x 3a = -12a
-5a -12a (bc they're like terms) = -17a
then, -4 x -1= 4 ( two negs cancel each other out)
I apologize for my mistake the first time

(a) What additional information is needed to prove the triangles are congruent by ASA Postulate? Explain.
(b) What additional information is needed to prove the triangles are congruent by the HL Theorem? Explain.
Answer:
A)
The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
B)
H-L (Hypotenuse-Leg) Congruence Theorem. If the hypotenuse and leg in one right triangle are congruent to the hypotenuse and leg in another right triangle, then the two triangles are congruent.

Evaluate for a:
69 = 13 - 7/12a
Answer:
-96
Step-by-step explanation:
69-13=13-7/12a-13
56=-7/12a
56 times 12=-7/12 times 12
672=-7a
Move negative over
-672=7a
-672/7=a
a=-96

∠2≅∠4, m∠2=110°. Find the measures of angles 1, 3, and 4 and explain how you know.
∠2 ≅ ∠4 = 110° [exterior alternate angles are equal]
∠1 = 180° - 110° = 70° [since angles on a line have a sum of 180°]
∠1 = ∠3 = 70° [since vertically opposite angles are equal]
2. Find the value of x.

(5x)
(3x+28)
O 14
O20
O 12
O 19
Answer:
x = 14
Step-by-step explanation:
The triangle has 2 congruent legs and is isosceles with 2 base angles being congruent , then
5x = 3x + 28 ( subtract 3x from both sides )
2x = 28 ( divide both sides by 2 )
x = 14
how to solve
2(x+6)=4
x=?
Answer:
[tex]x=-4[/tex]
Step-by-step explanation:
[tex]2(x+6)=4~(Given)\\\\2x+12=4~(Distribute~2~to~x+6)\\\\2x+12-12=4-12~(Subtract~12~on~both~sides)\\\\2x=-8~(Simplify)\\\\\frac{2x}{2}=\frac{-8}{2}~(Divide~2~on~both~sides)\\\\x=-4~(Simplify)[/tex]
Answer:
[tex]\boxed {x=-4}[/tex]
Step-by-step explanation:
[tex]2(x+6)=4[/tex]
Divide both sides by 2 :
[tex]\cfrac{2\left(x+6\right)}{2}=\cfrac{4}{2}[/tex][tex]x+6=2[/tex]Subtract 6 from both sides:
[tex]x+6-6=2-6[/tex][tex]x=-4[/tex]______________________

Gabriella is building a garden that is 3.6 m long by 7.77 m wide. What is the area of her garden?
Find the missing side of the length, s. I need help!
Answer:
s = 12
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
[tex]\frac{AB}{XY}[/tex] = [tex]\frac{AC}{XZ}[/tex] , substitute values
[tex]\frac{6}{9}[/tex] = [tex]\frac{8}{s}[/tex] ( cross- multiply )
6s = 72 ( divide both sides by 6 )
s = 12

Which equations have the same pair of solutions? Select all that apply.
n(n + 3)(n - 4) = 0
2n(4n + 6)(6n - 4) = 0
0 = 2n(6 - 4n)(4 - 6n)
0 = n(2n + 3)(3n - 2)
2n(2n + 3)(3n - 2) = 0
3n(6n + 9)(9n - 6) = 0

The sum of the ages of Alice, Barbie & Cindy is 30. Alice is four times older than Cindy. Barbie is 3 years older than Alice. How old is Cindy?
A. 12
B. 21
C. 9
D. 3
E. 15
D.
Explanationbecause the number have 3
Step-by-step explanation:
A+B+C = 30
A = 4C
B = A+3
=> 4C+4C+3+C = 30
9C + 3 = 30
9C = 30-3
9C = 27
C = 3
Therefore, the age of Cindy is 3 years old
