Step-by-step explanation:
x = 7 cos 210 = 7×(-½√3) = -3.5√3
y = 7 sin 210 = 7×(-½) = -3.5
point C (-3.5√3 , -3.5)
c i think (answer needs to be 20 characters long)
Step-by-step explanation:
2×2 + 8x + 26 =0
4 + 8x + 26 =0
4 + 26 = 0-8x
30 = 8x
divide both sides by th coefficient of x
30
=<em>3.75</em>
Answer:
-3
Step-by-step explanation:
1/2x2=1 1-4=-3
For long division, you would put 700 in the middle, since the fraction would be 700/21. Then you would figure out how many times 21 goes into 700. Then you would subtract 700 by the amount it would be before it went above 700 by multiplying it by 21. Then, if it is not able to go into 700 fully, you would put a decimal and bring a 0 down.
