Answer:

p(x)=-8(x+4)^2+128

Step-by-step explanation:

Given, p(x)=-8x^2-64x

Take -8 factor common,

p(x)=-8(x^2+8x)

which can be written as

p(x)=-8(x^2+2 \times 4x)

Add and subtract by 16 inside bracket,

p(x)=-8(x^2+2 \times 4x+16-16)

p(x)=-8((x^2+2 \times 4x+4^2)-16)

p(x)=-8((x+4)^2-16)

p(x)=-8(x+4)^2+8 \times 16

p(x)=-8(x+4)^2+128

Mika can eat 21 hot dogs in 6 minutes. She wants to know how many minutes (m) it would take her to eat
kipiarov [429]

Answer:

The answer is 10 minutes.

Step-by-step explanation:

First, convert the known amount of time to a fraction.

6/21 (min over hot dogs).

Set up a proportion.

6/21 = m/35 (m being the number of minutes)

Cross multiply.

210 = 21m

Solve for m. (divide each side by 21)

m = 10

I hope this helps! :)

Okay so for number one you use PEMDAS so you can either divide 144 by 12 first or multiply 5 and 6 or divide 6 by 3. 
Normally, I do multiplicarion first so the first step would be to multiply 5 and 6 with is 30 so the new equation is 144/12+30/3 okay and then do the divisions.
So the new equation would be 12+10 and which equals 22 

And for number two since you have a variable you can't use PEMDAS so just distribute the 11 but only to the ones in the parentheses. 
So the new equation turns out to be 11x-33+5=0 
Okay then, since you need to figure out what x is, you move over -33 and 5 by adding 33 and subtracting 5 which gives you 11x=33-5 
And then just solve 11x=28 and x is a decimal number. (x=2.55)
