Answer:
x = 26
Step-by-step explanation:
because JKL is 90 degrees
x+8 + 2x+4 =90
3x + 12 =90
3x = 78
x = 26
Take half of the coefficient of x: It is 3, and half that is 3/2.
Then <span>x^2+3x=6 becomes:
</span><span> x^2+3x + (3/2)^2 =6 + (3/2)^2, and
(x+3/2)^2 = 6 + 9/4
You were not asked to solve the equation, but why not do it for the practice?
</span>Solve (x+3/2)^2 = 6 + 9/4 for x. There will be 2 values.
Answer:
G
Step-by-step explanation:
9+(-3) = 6
→ 
8 and 10 can both be divided by 2. So, 8 ÷ 2 is 4 and 10 ÷ 2 is 5.
Hope this helps :)
Answer:
66.666666666667% error
Step-by-step explanation:
Percent Error = Vobserved - Vtrue / Vtrue
= 9 - 27 / 27
= -18/27
= -66.666666666667%
= 66.666666666667% error
I hope this helps!
