Answer:

46

Step-by-step explanation:you would start with substituting 20 wher "C" is which makes your equation 2(20)+6, then you'd multiply 2x20 which is 40 then add 6 (40+6) which comes out to 46 :)

neonofarm [45]

Answer:

8

Step-by-step explanation:

f(x)=2x^4-4x^3-11x^2+3x-6

f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3(-2)-6

f(-2)=2(16)-4(-8)-11(4)-6-6

f(-2)=32+32-44-12

f(-2)=64-44-12

f(-2)=20-12

f(-2)=8

Answer:

0.75 (75%) of a bag

Step-by-step explanation:

The question states that Frank has 3 bags and 4 bird feeders. In order to know how much of the bags he needs to add to each feeder, we are going to need to divide the amount of bags by the amount of feeders. This in term will give us an equal amount that should be added to each feeder.   ... simplify We see from the calculation above that each feeder will get an equal amount of 0.75 (75%) of a bag.

Solving Rational equations. LCD method. Show work. Image attached.
Dmitry [639]

Answer:

b=1

Step-by-step explanation:

The given rational equation is

\frac{2b-5}{b-2} -2=\frac{3}{b+2}

The Least Common Denominator is (b+2)(b-2).

Multiply each term in the equation by the LCD.

(b+2)(b-2)\times \frac{2b-5}{b-2} -(b+2)(b-2)\times2=(b+2)(b-2)\times\frac{3}{b+2}

Simplify;

(b+2)\times \frac{2b-5}{1} -2(b+2)(b-2)=(b-2)\times\frac{3}{1}

(b+2)(2b-5) -2(b+2)(b-2)=3(b-2)

Expand and group similar terms

2b^2-5b+4b-10 -2(b^2-4)=3b-6

2b^2-5b+4b-10 -2b^2+8=3b-6

-b-2=3b-6

3b+b=-2+6

4b=4

b=1
