Answer:
x = 10
Step-by-step explanation:
The line from the vertex to the base is a perpendicular bisector.
Consider the left side right triangle, eith base =
x
Using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
(
x )² + 7² = (
)², that is
x² + 49 = 74 ( subtract 49 from both sides )
x² = 25 ( multiply both sides by 4 to clear the fraction )
x² = 100 ( take the square root of both sides )
x =
= 10
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is
.
We need to find the factor of this trinomial.
![x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)](https://tex.z-dn.net/?f=x%5E%7B2%7D-6x-16%3Dx%5E2-8x%2B2x-16%5C%5C%5C%5C%3Dx%28x-8%29%2B2%28x-8%29%5C%5C%5C%5C%3D%28x%2B2%29%28x-8%29)
The factors of
is (x-2) and (x-8).
So, the factor of
is (x-8). Hence, the correct option is (B).

Answer: Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
