Answer:
Step-by-step explanation:
that would be : (-7x + 4)(-7x - 4)
because the difference of squares is a^2 - b^2.....but when factored, u get :
(a + b)(a - b)
Answer:
Part 1)
Part 2)
Step-by-step explanation:
Part 1) Find the measure of angle Z
we know that
In the right triangle XYZ of the figure
The tangent of the angle Z is equal to divide the opposite side to angle Z by the adjacent side to angle Z
so
substitute the given values
Part 2) Find the measure of angle Y
we know that
In the right triangle XYZ of the figure
The tangent of the angle Y is equal to divide the opposite side to angle Y by the adjacent side to angle Y
so
substitute the given values
The number that only has 2 factors which are itself and 1 is called a prime number, in this case it would be 11.
