(x-4)^2=36
take square roots,
± (x-4) =6
=>
x-4=6 => x=10
-(x-4)=6 => x-4 = -6 => x=-2
Answer:
9 cm
Step-by-step explanation:
Given that angle Y = 90 means that the triangle is a right angle triangle
If angle X = 30 degrees and xz =18 cm
xz is the hypotenuse side while zy is the opposite side considering the angle at X
Hence using the notation SOH CAH TOA
SOH
Sin X = zy/xz
Substituting
Sin 30 = zy/18
cross multiply
zy = 18 sin 30
zy = 18 * 0.5
= 9 cm
The answer is (x+7)(x-4)
hence, the solution should be C
