Answer:
A. 6(1+2x)
Step-by-step explanation:
we take 6 as Common factor out of the equation
1 meter = 1000 mm
so then 5 meters is just 5 * 1000 = 5000 mm.
B. Is the right answer
First you have to take the common elements then use an identity/formula to get the rest
x^3 - 3x^2 + x-3
x^2 (x-3) +1 (x-3)
(x^2 +1) (x-3)
(x-1)(x+1)(x-3) {using a^2-b^2 on x^2-1^2}
Answer:
x = 4
Step-by-step explanation:
We can find RT
sin theta = opposite / hypotenuse
sin 60 = 2 sqrt(3) / RT
RT = 2 sqrt(3) / sin 60
RT = 2 srt(3) / ( sqrt(3) / 2)
RT = 4
tan theta = opp/ adjacent
tan 45 = x / RT
tan 45 = x / 4
4 tan 45 = x
4 * 1 = x
4 = x
