Answer:
Its A :))
Step-by-step explanation:
Express<span> the prime </span>numbers<span> 7, 15, and 261 as the </span>difference of two squares
you add up 138+225 and you get 363 then you subtract 482-363 this is how you set it up:
4 8 2
- 3 6 3
------------
you have to borrow because 3 does not go into 2 so you change the 8 into a 7 then you 10 to 2 and you get 12 so this is what it looks like:
4 7 12
- 3 6 3
-------------------
so you then subtract 12-3=9 then 7-6=1 then 4-3=1
so this is what it looks like
4 7 12
--- 3 6 3
--------------------
1 1 9
so on Sunday they rode 119 miles
Answer:
A and A
the equation of a parabola in vertex form is
y = a(x - h)² + k
where ( h, k ) are the coordinates of the vertex and a is a multiplier
y = - 2(x + 3)² + 2 is in this form
with vertex = ( - 3, 2)
To find the y-intercept let x = 0
y = - 2(3)² + 2 = - 18 + 2 = - 16
Similarly
y = - 2(x + 2)² + 2 is in vertex form
vertex = ( - 2 , 2)
x = 0 : y = - 2(2)² + 2 = - 8 + 2 = - 6 ← y- intercept
hope this helped
