area white=(x+1) times (x+1)=x²+2x+1


big-white=(2x²+25x+50)-(x²+2x+1)=
2x²+25x+50-x²-2x-1=

Chen’s house is 53 years old. This is 5 more than twice the age of Sunny’s house, h.
tankabanditka [31]

Answer:

The Equation which shows the equality is 53 = 2 h + 5 ,

The age of Sunny's house is 24 years old

Step-by-step explanation:

Given as ;

The age of the house of Chen's is 53 years old

Let the age of of the house of sunny = h years old

So, according to question

Chen's house age is 5 years more than twice the age of sunny's house

I.e Chen's house age = 2 × sunny's house age + 5

Or, 53 = 2 × h + 5

or,  2 × h = 53 - 5

so . 2 × h = 48

∴    h = \frac{48}{2} = 24 years

Hence The Equation which shows the equality is 53 = 2 h + 5 , And The age of Sunny's house is 24 years old .  Answer

What 3 numbers can you multiply to get 160?
timama [110]
Three numbers you can multiply to get 160. First, we make an equation.

Since 160 is divisible by 4, we will make the equation this.

(#1 * #2 * 4 = 160)
 Divide 160 by 4, and you get this. #1 * #2 = 40

Now, we divide 40 by 2. 

The final answer is 2, 20, and 4.

2x20x4= 160

Can someone pleaseeeee help me
polet [3.4K]
A question like this should be answered by first looking at the number and the numbers you are given and making an estimate, testing it, and repeating if it is incorrect. It is relatively simple and I would like you to at least try a couple of times with an estimate of your own. If you really do have trouble with this, I will put the answers in a second. To make sure you understand the concept I will answer 3 of the 4 and you can try the last one. I will also just state the number of steps and leave the most of the expression writing to you.   ;)     

A. 8 feet forward, 8 feet forward.  8×2 or 0 + 8 + 8

B. Probably the hardest. Good thing you get to do it :)

C. 6 feet forward, 5 feet forward. 0 + 6+5 or 0 + 5+6 (This shows the commutative property)

D. 8 feet forward, 5 feet back. 0 + 8 - 5 or 0 - 5 + 8.

(You Don't Need the 0's in any of them unless you are showing the starting point which you probably are required to do, but since technically the Cecil starts at 0,  added the 0 as the point at which to start your expression.)
