The area of a rectangular wall of a barn is 144 square feet. Its length is 10 feet longer than the width. Find the length and width of the wall of the barn.
The width is __feet.
Answers
Answer:
8 feet
Step-by-step explanation:
Let l and w be length and width, respectively. Then:
lw=144 and
l=w+10
So:
w(w+10)=144
w²+10w-144=0
(w+18)(w-8)=0
w=8 as the width ................
The width of the rectangular wall is 8 feet.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Let l and w be length and width, respectively. Then:
l x w=144
l = w + 10
The area will be given as;-
w(w+10)=144
w²+10w-144=0
(w+18)(w-8)=0
w = 8 and -18 ignore -18.
Therefore the width of the rectangular wall is 8 feet.

Answer:
7p¹⁵/ 3q¹²
Step-by-step explanation:
From the question given above,
28p⁹q¯⁵ / 12p¯⁶q⁷
To know which of option is equivalent to the above expression, we shall simplify the expression as shown below:
28p⁹q¯⁵ / 12p¯⁶q⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷
Recall:
Xᵐ ÷ Xⁿ = Xᵐ ¯ ⁿ
Therefore,
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (28/12)p⁹ ¯ ¯⁶q¯⁵ ¯⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p⁹⁺⁶q¯¹²
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p¹⁵q¯¹²
Recall:
X¯ⁿ = 1/Xⁿ
Therefore,
(7/3) p¹⁵q¯¹² = (7/3) p¹⁵ × 1/q¹²
(7/3) p¹⁵q¯¹² = 7p¹⁵/ 3q¹²
Hence,
28p⁹q¯⁵ / 12p¯⁶q⁷ = 7p¹⁵/ 3q¹²

H) Slope -1/4 and y-intercept -1.5
Step-by-step explanation:
The slope of the line is determined by the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]
We can use any two points on the line lets use the ones that are shown, (-6 , 0) and (2 , -2).
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-2-0}{2-(-6)} \\\\m=\frac{-2}{8}\\\\m=-\frac{1}{4} \\[/tex]
and the y-intercept is shown in the graph where the line crosses the y-axis
In this case the line crosses the y-axis between -1 and -2 which is -1.5
so the value of slope is -1/4 and the value of y-intercept is -1.5 .So third option is our answer.

the average rate of change of the function f(x) on the interval -3≤x≤3 is -2.5. If (-3)=14 then which of the following is the value of f(3)?
Answers
The average rate of change of f(x) on -3 ≤ x ≤ 3 is given to be
(f (3) - f (-3)) / (3 - (-3)) = -2.5
If f (-3) = 14, then
(f (3) - 14) / (3 + 3) = -2.5
(f (3) - 14) / 6 = -2.5
f (3) - 14 = -15
f (3) = -1
