Answer:
6
Step-by-step explanation:
(whole secant) * (external part) = (tangent)^2
(KL) * (KM) = KJ^2
(KM+ ML) * KM = KJ^2
(2+ ML) * 2 = 4^2
(2+ ML) * 2 =16
Divide each side by 2
(2+ ML) = 8
Subtract 2 from each side
ML = 6
Answer:
a) x=5
b) x=6
Step-by-step explanation:
a)
3x+7=180-(10x-22)
3x+7=202-10x
13x=195
x=5
b)
11x-3=4x+39
7x=42
x=6
I am so sorry I forgot what the formula names are but these are the correct solutions. It has been a while since I've done Geometry.
Using distributive property 16y+144+24y could be one :) or: 40y+144
Yes! To factor this, you would put it into expanded form: (x+7)(x-7). This is the only way to solve this and eliminate the x^1 term.
