Help me please !!! ASAP

When multiplying numbers a negative number will make a positive into a negative. Yet if multiplied again by another negative it will cancel out or make it positive again. Seeing as answer c has only one negative it's the correct answer.

In expansion of (2x+1)(x^2+px+4), the coefficient of x is twice the coefficient of x^2.
Brilliant_brown [7]

You're probably supposed to find the value of p and not x, which is impossible to do.

Expanding gives

(2x+1)(x^2+px+4)=2x^3+(1+2p)x^2+(8+p)x+4

We're told that

8+p=2(1+2p)

which we can use to solve for p:

8+p=2+4p

6=3p

\boxed{p=2}

Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyra
mina [271]

Answer:

Akira needs 45 square inches of  gold foil to cover the chair free including the bottom​

<u>Step-by-step explanation:</u>

Total surface  =  surface area of the base square + area of 4 triangles

<u>Step 1: The surface area of the base square</u>

surface area of the base = surface area of the square =  s^2

where s is the side length

The the surface area of the base  = 3^2 = 9 square inches

<u>Step 2: The surface area of the side triangles </u>

The area of the triangle = \frac{1}{2}\times \text{side length} \times \text{slant height}

On substituting the values,

The area of the triangle =\frac{1}{2} \times 3 \times 6

The area of the triangle = \frac{18}{2}

The area of the triangle = 9 square inches

Now the area of 4 triangles  =  4 x 9  = 36 square inches

Thus the total surface area  =  9 + 36 = 45 square inches

Solve for n: 6n+12=6
arlik [135]

Hey there! :)

6n + 12 = 6

Isolate our given variable.

We can do this by subtracting both sides by 12.

6n + 12 - 12 = 6 - 12

Simplify.

6n = -6

Divide both sides by 6.

6n ÷ 6 = -6 ÷ 6

Simplify.

n = -1

~Hope I helped!~
