The length of a rectangle is 20 units more than its width. The area of the rectangle is x4−100.

Mice21 [21]

Answer:

$1. x^2-10$ because the area expression can be rewritten as $(x^2-10)(x^2+10)$ which equals $(x^2-10)((x^2-10)+20).$

Step-by-step explanation:

Area of the rectangle $=(x^4-100)$

$x^4-100=(x^2)^2-10^2\\$Applying difference of two squares: a^2-b^2=(a-b)(a+b)\\(x^2)^2-10^2=(x^2-10)(x^2+10)$

Since the length of a rectangle is 20 units more than its width.

$Width: x^2-10\\Length=x^2+10=x^2-10+20$

The correct option is therefore 1.

Volume of a Cylinder: V = πr²h

V is volume
r is radius
h is height

Step-by-step explanation:

Step 1: Identify

Radius r = 12 ft

Height h = 19 ft

Step 2: Find Volume

Substitute in variables [Volume of Cylinder]: V = π(12 ft)²(19 ft)
Evaluate exponents: V = π(144 ft²)(19 ft)
Multiply: V = 2736π ft³
Substitute π: V = 2736(3.14) ft³
Multiply: V = 8591.04 ft³

The area of a triangle is 15x^4+3x^3+4x^2-x-3 square meters. The length of the base of the triangle is 6x^2-2 meters. What is th

MArishka [77]

Answer:

The height of the triangle is: $H = (5x^2 + x +3)$

Step-by-step explanation:

Here, the area the triangle is given as: $15x^4 + 3x^3 + 4x^2 - x - 3$

Also, base of the triangle = $(6x^2 -2)$

Let us assume the height of the triangle = H units

Now, AREA of TRIANGLE = $\frac{1}{2} \times B \times H$

$\implies (15x^4+3x^3+4x^2-x-3 ) = \frac{1}{2} \times ( 6x^2-2) \times H\\\implies H =\frac{ (15x^4+3x^3+4x^2-x-3 )}{(3x^2-1)}$

Solving by LONG DIVISION, we get:

$H = (5x^2 + x +3)$

Hence, the height of the triangle is: $H = (5x^2 + x +3)$

The given triangle is a Right angled triangle,

So, by applying Pythagoras theorem :

${c}^{2} = {12}^{2} + 9 {}^{2}$

=》

${c}^{2} = 144 + 81$

=》

${c}^{2} = 225$

=》

${c} = \sqrt{225}$

=》

$c = 15$

hence, value of c = 15 mi
