If your looking for the number w the Variable for 64, its 64f standing for “64 feet”
Answer:
roots: -2 and 5
Step-by-step explanation:
What are the roots of y = x2 – 3x - 10?
we see...
factor -10 .... using the X-method.
-10 = 2 * -5
where 2 + -5 = -3
so
y = (x +2)(x - 5)
roots are -2 and 5
This problem exercises the concept of "similar triangles."
With similar triangles, we can compare the sides using ratios.
The equation we can use to find side A is stated below.
Side 1A / Side 1B = Side 2A / Side 2B
The number refers to the triangle, and the letter refers to the side of each triangle. Side A in both triangles must be the base of the triangle, and side B in both triangles can be either of the other sides. The only restriction is that once we pick a side B on triangle 1, we must pick that same side on triangle 2.
A / 7 = 3 / 2
Then we can solve for the length of side A.
A = 7*3/2 = 21/2 = (E) None of These
3x + 2y = 12
x = y - 1
3x + 2y = 12
3 (y - 1) + 2y = 12
3y - 3 + 2y = 12
5y - 3 = 12
5y = 15
y = 3
x = y - 1
x = (3) - 1
x = 2
answer:
(2, 3)
