9/8=12/p -----> divide by 12 on both side
9 1. 9
-- x -- = ---- = 8
8 12. 72
p=8
hope this helped:)
Answer:
k = 3
Step-by-step explanation:
Expanding the first term, we find 1/x at 10(kx)²(1/x)³ = 10k²/x
Expanding the first term, we find 1/x at 8*1⁷(-2/x)¹ = -16/x
Then
10k² - 16 = 74
k = 3
Answer:
x=3
Step-by-step explanation:
Answer:
x = 30
b = 30
a = 90
Step-by-step explanation:
So first let's find the 'X'
we already know one angle - 30 degrees
i think you should know the straight equals 180 so we minus 180 to 30
- 180 - 30 = 150
then we know there is 2x and 3x, which is unknown so in this we actually divide 150 with 5 cause 2 + 3 = 5, to get the x value
so x = 30
____________________________________________________
so you know the progress so I will write the answers now
x = 30
b = 30
a = 90
___
so just to check the answers I will add all the numbers to equal it to 360
30 + 90 + 60 + 30 + 60 + 90 = 360
Answer:
x^4 - 256
Step-by-step explanation:
We learn that: a^2 + b^2 = (a+b) * (a-b) so in this case:
(x² + 16)(x² - 16)
= (x^2)^2 - 16^2
= x^4 - 256
Hope this helped :3
