Answer:
B
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - 
y = 3x² + 6x + 1 ← is in standard form
with a = 3 and b = 6 , then
= - 
= - 1
Substitute x = - 1 into y for corresponding y- coordinate
y = 3(- 1)² + 6(- 1) + 1
= 3(1) - 6 + 1
= 3 - 5
= - 2
vertex = (- 1, - 2 )
Ah well this would look like 2(30) + 30 = 90 aka 2L + W = 90
Answer:
285, 629, 7392, 15708,43695
Step-by-step explanation:
If you add the digits of the number together, it should be divisible by 9. If it isn't, then it must be a multiple of only 3, not 9.

Hope this helped
Step-by-step explanation:
Solution:
(a) is the vertical direction, the force of gravity
on the object (or the wight force: w = Mg ) pulls the crate down while the surface reaction. N. pushes it 103N
rd, as shown:
w = Mg = (20.0kg 9.8m s3 - 196N
N- 196N as well
(b) In the horizontal direction, in the absence of
friction, there are two forces: (F) and the 53-N force. Applying the Newton's 2nd law helps the calculation of the unknown force. F. F - 53N (20.0 kg)(2.5 m 3
F = 103N plz mark me as brainliest
