X=3 y=-2
4x - 6y
4(3) - 6(-2)
12 - (-12) (two negatives cancel out)
12 + 12 = 24
answer: 24
Radical 63 can be broken down as radical 9 and 7. Radical 9 can be also 3 and you carry the radical 7. So radical 63 is basically 3 radical 7.
Answer: 117
if angle BCD=27 cause its a smaller angle. smaller than 90
then ABC=117 cause its a bigger angle. It is more than 90 and less than 180
the other three are way too big to compare it to the angle is providing (ABC).
hope i helped a little
Answer:
5.05*10³
Step-by-step explanation:
-
<em>Put the decimal after the first digit and drop the zeroes. To find the exponent count the number of places from the decimal to the end of the number.</em>
- 5050 = 5.05 *1000 = 5.05*10³
Answer:
1. D 2. B 3. C
Step-by-step explanation:
WARNING: I am not 100% sure about 2.
1. If you simplify the first part of the equation for letter D, you'll realise it is the same equation.
2. It is either B or D. I believe it is B because you would not have to multiply 4 again.
3. The square root of 121 is eleven, the square root of x^2 is x. x=11.
