Sure.
Can you find a number that goes into both terms, 5k and 35 ?
How about 5 ?
(5k - 35) = 5 times (k - 7) .
Answer:
0.28277
I got this by plugging in 0.2512 for "A" ( A = π r² ) Then I solved the rest ( divide both sides by pie, then taking the square root from that.

Answer:
(3y+2)(y+7)
Step-by-step explanation:
I think you meant (y+7)+3y(y+7)+(y+7). Anyways, we have to count the number of (y+7) there are. The first term tells us we have 1 group. The second term tell us we have 3y groups. The last term tells us we have 1 group. Therefore we have 1+3y+1 groups of y+7 which gives us (3y+2)(y+7)
Answer:
(14, -9)
Step-by-step explanation:
So you can solve this using substitution. When you're solving a systems of equations, you're looking for when (x, y) is the same for both equations, or in other words where the two linear equations intersect. Because of this we can solve for x or y in one equation and substitute it into the other equation, since the x and y in one equation should equal the x and y in the other equation.
Original equation:
x + 2y = -4
Subtract 2y from both sides
x = -2y - 4
Original equation:
2x + 3y = 1
Substitute -2y -4 as x
2(-2y - 4) + 3y = 1
Distribute the 2
-4y - 8 + 3y = 1
Combine like terms
-y - 8 = 1
Add 8 to both sides
-y = 9
Multiply both sides by -1
y = -9
So now that you know what y is, you can plug it into either equation to solve for x:
x + 2y = -4
Plug in -9 as y
x + 2(-9) = -4
Multiply
x - 18 = -4
Add 18 to both sides
x = 14
So this gives you the solution (14, -9)
Hi there
This is a smart question, so let me show you the trick of it.
176 feet per second
but we dont know per minute
We know that 60 seconds = 1 minute
with that information we can solve it
If 176 .......... 1 second
x .............. 60 second
x = 176 * 60
x= 10560
He is falling 10560 feet per minute
