Answer:x^2 + 9x + 20
Step-by-step explanation:
You could just multiply (x+4)(x+5) and get x^2 + 9x + 20, but judging from the picture, it looks like they want you to split it into 4 rectangles
x^2 +4x+ 5x + 20 =x^2 +9x + 20, just like (x+4)(x+5)
Answer:
The capacity of the mug =
cups
Step-by-step explanation:
Given - A mug is 1/8 full. The mug contains 1/6 of a cup of water.
To find - Find the capacity of the mug. Write the answer as a fraction or mixed number
Proof -
Let the capacity of water = x
Given that,
A mug is
full of water
⇒Total cups of water in the mug = 
Now,
Given that, The mug contains
of a cup of water.
∴ we get
=
⇒x =
× 8
=
=
= 
⇒x = 
∴ we get
The capacity of the mug =
cups
Answer: 
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[switch x and y]
[subtract both sides by 3]
[multiply both sides by 2]

Now, we know that
.
Answer:
It's totally correct with no doubt
