Answer:
The length is 88.90 cm
=========================
Area equation of a rectangle
A = lw, where A - area, l - length, w - widthGivenA = 8712 cm²w = 98 cmFind the length8712 = 98ll = 8712/98l = 88.90 (rounded)Answer:
Length = 88.9 cm
Step-by-step explanation:
Formula we use,
→ A = L × W
Then the value of its length is,
→ A = L × W
→ 8712 = L × 98
→ L = 8712/98
→ L = 88.8979591837
→ [ L = 88.9 cm ]
Hence, the length is 88.9 cm.

Why do we use parenthesis if an interval is infinite on both boundries?
We use parenthesis if an interval is infinite on both boundries in order to exclude end-points .
Square brackets mean the set of all points from a to b .
If we use square brackets , it would mean we are including - infinity and + infinity , which is practically impossible .
When we , use parenthesis only the nos . lying between the two points are taken into consideration , the two points are not included .

One triangle shown is formed by the tree, its shadow, and a line of sight from the ground to the top of the tree. The other is formed by Manny, his shadow, and a line of sight from the ground to the top of his head. Are the two triangles similar?
The height of the tree is 21 feet if manny stands 512 feet tall, and his shadow is 414 feet long. The tree's shadow extends 17 feet in length.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
The length of Manny's shadow, which is 414 feet long, is 512 feet.
The tree's shadow extends 17 feet.
Here, we'll assume that the height is x.
According to the data given, the calculation is as follows:
414 : 512 = 17 : x
⇒ 414 / 512 = 17 / x
⇒ (414)x = (512)(17)
⇒ x = (512)(17)/(414)
⇒ x =21.02
⇒ x = 21 feet
Therefore, the height of the tree is 21 feet if manny stands 512 feet tall, and his shadow is 414 feet long. The tree's shadow extends 17 feet in length.

5 times a number is 36 less than the square of that number. Find the negative solution.
In linear equation , the negative solution is x = -4 .
What is a formula for linear equations?
A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. (b). Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.Let's assume that the number is x
Now according to the question,
When 36 is subtracted from the square of a number, the result is 5 times the number.
x² -36 = 5x
x² -5x -36 = 0
x²- 9x + 4x -36 = 0
x ( x - 9) +4( x - 9 ) = 0
(x-9) ( x + 4 ) = 0
x = 9 , -4
So the negative solution is x = -4

Answer:
x + y = -3.
Step-by-step explanation:
x + y = 2y = -x + 2 - the slope of this line is -1 . The line parallel to it will also have a slope of -1.It also passes through (-7,4) so we havey - 4 = -1(x - -7)y - 4 = -1(x + 7)y - 4 = -x - 7x + y = -3 is the required equation.
In the expansion of (1 + ax)24 where a > 0, the coefficient of x² is 1104. Find the value of a.
The required value of a is 2 if the coefficient of x² is 1104 of the expansion (1 + ax)²⁴.
What is the Binomial Theorem?According to the binomial theorem, it is possible to expand any non-negative power of binomial (x + y) into a sum of the form,
(x+y)ⁿ = ⁿC₀xⁿy₀ + nC₁ xⁿ⁻¹y₁ + nC₂ xⁿ⁻² y2 + ... + nC x¹yⁿ⁻¹ + nCn x°yⁿ
where n ≥ 0 is an integer and each ⁿCₓ is a positive integer known as a binomial coefficient.
We have been given that the expansion as
(1 + ax)²⁴
As per the binomial theorem expansion of the term 3,
T₃ = ⁿC₂ a² x²
Since the coefficient of x² = 1104
⇒ n!/2!(n-2)a² x² = 1104
Here n = 24
⇒ 24!/2!(24-2)a² = 1104
⇒ 276a² = 1104
⇒ a² = 1104/276
⇒ a² = 4
⇒ a = 2
Therefore, the required value of a is 2 if the coefficient of x² is 1104 of the expansion (1 + ax)²⁴.
