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.

58 times 100 equal I don't no

Answers

The answer is 58 x 100 = 5800 because you add the two 0's at the end of each number.
So for example, if you do 35 x 1000, you just add the number of 0's to the number so the answer would be 35000.
Hope this Helps! :D

It equals 5,800. Good Luck In School!

Nick has $7.00. Bagels cost $0.75 each, and a small container of cream cheese costs $1.29. Write an inequality to find the numbers of bagels Nick can buy. Identify what your variable represents

Answers

Since the question only asks for bagels, put the cream-cheese idea aside.
The total spent has to be less than $7 so an equation can be this: $0.75x<$7 where x is the number of bagels

I need help solving this problem 7/10 + 4 =

Answers

7/10=.7
.7+4=4.7
that is the answer

If you need in fractions...
7/10 + 4 = 4 and 7/10
You get this by just adding the whole number to the fraction. Or, do it this way...
7/10 + 4/1 : find LCD to get 10.
=7/10 + 40/10
= 47/10
= 4 and 7/10
