Answer:
The area would be '15l - l²
Step-by-step explanation:
Given,
By 30 feet of wire fencing we need to make a rectangular shape,
Thus, perimeter of such rectangle = 30 feet,
We know that,
Perimeter of a rectangle = 2( length + width)
if length = l feet,
⇒ 2(l + width) = 30
⇒ 2l + 2 × width = 30
⇒ 2 × width = 30 - 2l
⇒ width = = (15-l) feet,
Now, area of the rectangle,
A = length × width
= l × (15-l)
= 15l - l²
Which is the required polynomial expression.
Note :
Polynomial expression : an expression having terms consisting coefficients and variables separated by addition, subtraction and multiplication.
Round off the decimals to a sensible number.
So 3.7 would be 4 and 10.2 would be 10.
In this case, it would be (2 × 4 + 8) × 10 which is 160.
X + x + 2 = 90
2x + 2 = 90
-2. -2
to combine like terms
2x = 88
Divide both sides by 2 to isolate x
x = 44
Answer
A is x+2 = 46
B is x = 44
Total 90 degrees = complementary angle
Answer:
Step-by-step explanation:
Slope intercept form is:
<h2>
Find the Slope:</h2>
Choose 2 points on the graph:
(0,1) (2,0)
Find the slope of the two points:
<h2>Find the Y-Intercept</h2>
The y-intercept, or the point that the line crosses on the y axis, is (0,1).
Answer:
8x + 2
Step-by-step explanation:
Like terms:
6x and 2x
-3 and 5
6x + 2x = 8x
5 - 3 = 2
8x + 2
