I need help please... 30 points + brainliest if u answer all 5 PLEASE SOMEONE... I'll do anything you want... 1. f(x)=x^2−4x, find f(−3)

2. f(x)=x^2−x, find f(−10)

3. f(x)=3x+1, find f(−3)

4. f(x)=4x−2, find f(8)

5. f(x)=x^2+2, find f(0)

1. x(x-4)

2. x(x-1)

4.2(2x-1

sorry I couldn't answer 3,and 5

I only know 3 of them.

I hope this helps

have a great day

1. 2±√x+1=y

2. 25−35+10=0

3. f(3)=10

4. =4+2=6

5. f(x2+2)=7∣∣x2+2−2∣∣=7∣∣x2∣∣=7x2

Step-by-step explanation:

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
