Find the area of the rectangle polynomial

Answers

Answer:

$\Longrightarrow: \boxed{\sf{8x^2+12x-8}}$

Step-by-step explanation:

Using the distributive property, you multiply by the area to find the area of the rectangle polynomial.

$: \Longrightarrow \sf{(Area)= (2x+4)*(4x-2)}$

Solve.

(2x+4)*(4x-2)

Multiply by expand.

Use the distributive property.

Distributive property:

⇒ A(B+C)=AB+AC

Use the FOIL method.

FOIL method:

$\Longrightarrow: \sf{\left(A+B\right)\left(C+D\right)=AC+AD+BC+BD}$

$\Longrightarrow: \sf{2x\cdot \:4x+2x\left(-2\right)+4\cdot \:4x+4\left(-2\right)}$

$\Longrightarrow: \boxed{\sf{=8x^2+12x-8}}$

Therefore, the correct answer is 8x²+12x-8.

I hope this helps! Let me know if you have any questions.

Knitting: You are knitting a blanket. You want the area of the blanket to be 24ft^2. You want the length of the blanket to be 2 feet longer than the width. What should the dimensions of the blanket be?

Answers

You can use factors to solve. Determine all the factor pairs of 24, find the two that are two numbers apart.
1, 24 X
2, 12 X
3, 8 X
4, 6 YES!

Algebraic way to solve using Quadratics:
l = 2 + w

A = lw

A = (2 + w)w Substitute (2 + w) for l

24 = (2 + w)w Substitute 24 in for the area

24 = 2w + w^2 Distribute

w^2 + 2w - 24 = 0 Set equal to 0 (put in standard form)

(w + 6) (w - 4) = 0 Factor

w + 6 = 0 and w - 4 = 0 Set each factor equal to 0.

So w= -6 or w = 4 ... -6 makes no sense for a length! So the width must be 4 and the length will be 4 + 2, which is 6.

True or False The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units

Answers

Answer:

True

Step-by-step explanation:

Given: Statement :"The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units"

We have to choose whether the given statement s true or false.

Consider the given statement.

The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units

We first find the area of circle with 14 units radius and area of a sphere with 7 units radius and compare the two values.

We know,

Area of circle = $\pi r^2$

given : r = 14 units

So, Area of circle = $\pi (14)^2$

Simplify, we have,

Area of circle = $196\pi$ units²

Now,

Area of sphere = $4\pi r^2$

given : r = 7 units

So, Area of sphere = $4\pi (7)^2$

Simplify, we have,

Area of sphere = $196\pi$ units²

Since, Area of circle with radius 14 units is equal to the area of sphere with radius 7 units.

Thus, The given statement is true.

The answer is true. The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units
