I need help please help me out I dont understand

24x² - 46x + 7

Step-by-step explanation:

Area of the shaded region = area of the larger square - area of the smaller square

✔️Area of the larger square = s²

= (5x - 4)²

= (5x - 4)(5x - 4)

= 5x(5x - 4) -4(5x - 4)

= 25x² - 20x - 20x + 16

= 25x² - 40x + 16

✔️Area of smaller square = s²

= (x + 3)² = (x + 3)(x + 3)

= x(x + 3) +3(x + 3)

= x² + 3x + 3x + 9

= x² + 6x + 9

✔️Area of the shaded region = (25x² - 40x + 16) - (x² + 6x + 9)

= 25x² - 40x + 16 - x² - 6x - 9 (distributive property)

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
