Can someone help me pls
Artist 52 [7]

Answer:

PΔJKL=66

Step-by-step explanation:

so we are given the line segments JK, KL, and LJ which are tangent to k(O), and also that JA=9, AL=10, and CK=14

JL=JA+AL (parts whole postulate)

JL=9+10=19 (substitution, algebra)

JA=JB=9 (tangent segments from the same point are congruent)

CK=KB=14 (tangent segments from the same point are congruent)

JK=JB+KB (parts whole postulate)

JK=9+14=23 (substitution, algebra)

LA=LC=10 (tangent segments from the same point are congruent)

LK=LC+CK (parts whole postulate)

LK=10+14=24 (substitution, algebra)

Perimeter of ΔJKL=LK+KL+LJ (perimeter formula for triangles)

Perimeter of ΔJKL=23+24+19=66 (substitution, algebra)

Match the polynomial on the left with the appriately factored expression on the right x^2-3x-18
Lapatulllka [165]

The factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)

<h3>How to match the polynomial?</h3>

The polynomial expression is given as:

x^2 - 3x - 18

Express -3x as 3x - 6x

So, we have:

x^2 + 3x - 6x - 18

Factorize the polynomial expression

x(x + 3) - 6(x + 3)

Factor out x + 3

(x + 3)(x - 6)

Hence, the factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)
