Answer:
C.KM = 15
D.KL = 17
F.Perimeter or triangle JKL = 50
Step-by-step explanation:
Given:
JL = 16,
KM = 4x-1
JK = 6x - 7
KL = 5x - 3
✔️Thus, let's find the value of x
Since KM is a perpendicular bisector of JL, it means JM = LM = ½*16 = 8
KM in ∆KJM is equal to KM in ∆KLM.
The angles opposite the two corresponding congruent sides in both triangles are also congruent to each other. Therefore, the third corresponding side and angles would be congruent to each other.
Thus:
JK = KL
6x - 7 = 5x - 3 (substitution)
Collect like terms
6x - 5x = 7 - 3
x = 4
✔️Find JK:
JK = 6x - 7
Plug in the value of x
JK = 6(4) - 7
JK = 24 - 7
JK = 17
✔️Find KM:
KM = 4x - 1
Plug in the value of x
KM = 4(4) - 1
KM = 16 - 1
KM = 15
✔️Find KL:
KL = 5x - 3
Plug in the value of x
KL = 5(4) - 3
KL = 20 - 3
KL = 17
✔️Find the Perimeter of ∆KLM:
Perimeter of ∆KLM = KM + KL + LM
= 15 + 17 + 8
= 40
✔️Find the Perimeter of JKL:
Perimeter of ∆JKL = JK + KL + JL
= 17 + 17 + 16
= 50.
The correct values are:
C.KM = 15
D.KL = 17
F.Perimeter or triangle JKL = 50
Answer:
7:3
Step-by-step explanation:
63:27
Divide both sides by 9
63 ÷ 9 : 27 ÷ 9
7:3
And you cannot simplify it anymore.
Hope this helped!

Answer/Step-by-step explanation:
[D]
Polynomials will be closed under an operation if the operation produces another polynomial. When multiplying polynomials, the variables' exponents are added, according to the rules of exponents.
(Note: exponents in polynomials are whole numbers.)

Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
<u>check</u>
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63
