Answer:
the answer is C 52ft
Step-by-step explanation:
first add 3.4 + 2.6 then you subtract your answer with 2.8
To find the tax, you multiply the tax rate by the amount to be taxed, so...350 × 7%
350 × .07 = $24.50
This is the amount of tax. Now add it to the original price for the total cost.
$350.00 + $24.50 =
$374.50
Answer:
x=πn, n∈Z
Step-by-step explanation:
if sin²2x=1-cos²2x, then
1-cos²2x-2cos2x+2=0; ⇒ cos²2x+2cos2x-3=0; ⇔ (cos2x+3)(cos2x-1)=0;
The answer is rather symbol just combine the like terms! -2X^2 has no like terms for it is the only exponent so cancel out C because it doesn't start with -2X^2. Next we add all variables with X but no exponent so 3X and -5x Add those together to get 3X +-5X which is -2X because the + is cancelled out so ghe equation is 3X-5X which equals -2X so get rid of everything but B. Finally to confirm it is B add all the basic numbers so the five and three to get eight. So (f+g)(x) = -2X^2 -2X + 8. The answer is B. (You guys said it was A so I changed it but now I know I am right.)
