Answer: 42
Step-by-step explanation: you would do 63 divided by 3 then you would get 21 and do 21×2 and get 42
Answer:
Square root of 4 is 2
so 1+![\frac{[1+\sqrt{2x-1]}^2 }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B1%2B%5Csqrt%7B2x-1%5D%7D%5E2%20%7D%7B4%7D)
=4
frac{[1+sqrt{2x-1]}^2 }{4}=3
so 1+sqrt{2x-1]}^2=12
so 1+sqrt{2x-1}=V12
sqrt{2x-1}=V12-1
2x-1=(V12-1)^2=12-2V12+1=13-2V12
2x=13+1-2V12
2x=14-2V12
x=7-V12
x=7-2V3

Step-by-step explanation:
The square root of 15 is irrational.
Step-by-step explanation:
step 1. graph f(x) = 2x + 6
step 2. y = mx + b. (slope intercept form)
step 3. b = 6 which is the y intercept so put a dot on (0, 6) or on the y axis at 6
step 4. m = 2 so put another dot up 2 and over to the right 1 from the y intercept
step 5. draw a line through your 2 points and you are done.
Answer:
5/8 * pi r^2
Step-by-step explanation:
First , you find the full area of the circle
A = pi r^2
Then multiply by the fraction that you want to find
5/8 * pi r^2
