The first one is 4
Second is 5/9
Third is 1/2
Fourth is 11
WXY = XYW ( = 41 ) ⇒ XYW is a isosceles triangle
⇒ XW = YW
⇒ 54 = 6x + 6
⇒ 6( x + 1 ) = 54
⇒ x + 1 = 9
⇒ x = 8
ok done. Thank to me :>
The answer is: 8 red marbles!
This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x
We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8
If this helped, give me brainliest :)
(3x^3 - 5x^2 -4x + 4) / (x-2) = (3x-2)(x+1) when x ≠2
Answer:
7
Step-by-step explanation:
24^2+b^2=25^2
576+b^2=625
<u>-576</u> <u>-576</u>
b^2=49
√b=√49
b=7
