Answer:
We have the next relation:
A = (b*d)/c
because we have direct variation with b and d, but inversely variation with c.
Now, if we have 3d instead of d, we have:
A' = (b*(3d))/c
now, we want A' = A. If b,c, and d are the same in both equations, we have that:
3bd/c = b*d/c
this will only be true if b or/and d are equal to 0.
If d remains unchanged, and we can play with the other two variables we have:
3b'd/c' = bd/c
3b'/c' = b/c
from this we can took that: if c' = c, then b' = b/3, and if b = b', then c' = 3c.
Of course, there are other infinitely large possible combinations that are also a solution for this problem where neither b' = b or c' = c
Take 1/2 of b and squaer it so
(b/2)^2 would complete the square
(sign doesn't matter becaus when squareing, sign goes positive)
c. (x + 5)(x - 7) use the FOIL method.
x² + 5x - 7x - 35
x² + (5x - 7x) - 35 collect like terms.
x² - 2x - 35
hope that helps, God bless!
Answer:
C
Step-by-step explanation:
Retangular prisms volume= lengthxwidthxheight
therefor you have to include all three number making you answer C
Answer:
x=37
Step-by-step explanation:
angles inside a triangle add up to 180
add all angles equal to 180
(x+10)+(3x-5)+(x)=180
remove parenthesis, combine like terms
5x-5=180
add 5 both sides
5x=185
divide by 5
x=37
angles: 37, 47, 106
