The inequality expression for the number of years when tree will be atleast 20 feets tall is x ≥14
- Growth rate = 1.3 feets per year
The height of the tree after x years can be represented as a linear equation thus :
<u>Number of years when the tree will be 20 feets tall</u> :
- 20 = 2 + 1.3x
- 20 - 2 = 1.3x
- 1.3x = 18
- x = 13.84
<u>The tree would be atleast 20 feets tall in 14 years x this can be expressed thus </u>

Answer:
You start the shelf 4 ft. 9 in. from the wall.
Step-by-step explanation:
The game plan is to take the length of the shelf away from the length of the wall, and then divide the remaining part into two equal pieces.
13 ft.
- 3 ft. 6 in.
12 ft 12 in,
- 3ft 6 in
9 ft 6 in.
9 ft. 6 inches divided by 2 equals 4.5 ft, 3 in.
.5 ft * 12 inches = 6 inches
You start the shelf 4 ft. 9 in. from the wall.
Answer:
x^2 +y^2
Step-by-step explanation:
Dude this is Pythragorean Theorem =)).
You may have missed this part of your lesson. It's ok and also not ok at the same time beacause pythagorean theorem is a meme.
Ok I'll explain once =)).
Thousands of years ago, a mathematician named Pythagore found out that if we have 3 squares, with one square's area equals to the sum of two other squares, then when we put the sides of the squares together to form a triangle , it'll always be a right triangle ( a triangle with one of its angle is 90°). A square area is measured by the length of its side multipled by itself. So he came up with the statement : In a right triangle, the length of the hypotenuse( the side that does not connect to the right angle) is equalled to the sum of squared other sides.
EG.
In this triangle, the right angle is ^ACB. If length of BC is <em>a</em><em>,</em><em> </em>length of AB is <em>c</em>, length of BC is <em>a</em>
A
I We have a formula :
I \ <em>a</em>^2 + <em>b</em>^2 = <em>c</em>^2
I \
I \
I <em>b</em> \ <em>c</em>
I \

I______\
C <em> a </em> B
So now you can use pythagorean theorem to show off =)).

A. The expression has two factors.
The two factors of the expression 7(2x+5) are 7 and (2x+5).
Hope this helps.
<u><em>Answer:</em></u>
Area of window = 3 ft²
Area to be painted = 45 ft²
<u><em>Explanation:</em></u>
To get the area to be painted, we will start by getting the area of the whole wall (including the window), then subtract from it the area of the window
<u>1- getting area of whole wall:</u>
From the figure, we can note that the length and width of the wall are given as 6 ft and 8 ft
Area of whole wall = length * width
Area of whole wall = 6 * 8 = 48 ft²
<u>2- getting area of window:</u>
Again, from the figure, we can note that the length and width of the window are 2 ft and 18 in (which is equivalent to 1.5 ft)
Area of window = length * width
Area of window = 2 * 1.5 = 3 ft²
<u>3- getting area to be painted:</u>
Area to be painted = area of whole wall - area of window
Area to be painted = 48 - 3 = 45 ft²
Hope this helps :)
