The answer is 460 because 460 is the nearest 10 to 50 (50+10)
To find g (f(x)) you should substitute "4x^2+x+1" to "x" of g(x) function. You'll havew:

To count (4x^2+x+1)^2 Just assume ( [4x^2+x] + 1)^2 and use the (a+b)^2=a^2+2ab+b^2 formula, where a=4x^2+x and b=1
Answer:
diameter of semicircle? ---> 30cm
perimeter- pi*r ----> 3.14159265 x 15 ---->47.12 cm
Step-by-step explanation:
The slope is -1/2. I know this because slope intercept of a line is y = mx + b. In the equation, y = -1/2 + 1/4, the slope is -1/2 and the y intercept is 1/4.
m stands for slope
b stands for y intercept
You would have to subtract 5 from her age so the equation would by y-5
