Answer:

For instance, there's the basic formula that the area of a triangle is half the base times the height. This formula only works, of course, when you know what the height of the triangle is. ... That is to say, the area of a triangle is half the product of two sides times the sine of the included angle.

Step-by-step explanation:

What is the answer to 18 - 3w = 4w

adelina 88 [10]

Answer:

Step-by-step explanation:

$18 - 3w = 4w$

Let's get all of the terms with the $w$ on the right-hand side of the equation, and everything else on the left-hand side of the equation.

To do this, we should add $3w$ to both sides of the equation to remove the $-3w$ from the left-hand side of the equation:

$18 - 3w + 3w = 4w + 3w$

$18 = 7w$

Finally, to get the $w$ by itself, we can divide both sides by $7$ :

$\frac{18}{7} = \frac{7w}{7}$

$w = \frac{18}{7}$

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too

Eddi Din [679]

Answer:

$\Large \boxed{ -x+65}$

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

$\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}$

$\displaystyle m=\frac{55-65}{10-0}=-1$

Use slope-intercept form

$y=mx+b$

$y=-1x+b$

<em>b</em> is the y-intercept, y-intercept is (0,65)

$y=-1x+65$

A cylinder has a height h, and a radius (3h-2)

tekilochka [14]

Answer:

$V= 4\pi (9h^2 -12h + 4)$

Step-by-step explanation:

Given

Shape: Cylinder

$Radius = 3h - 2$

$Height = h$

$Base\ Area = \pi (3h - 2)^2$

Required

Simplify the volume

The volume is calculated as:

$Volume = Base\ Area * Height$

Substitute values for Base Area and Height

$V= \pi(3h-2)^2*h$

Expand the bracket

$V= \pi(3h-2)(3h-2)*h$

Open brackets

$V= \pi (9h^2 -6h - 6h + 4) *h$

$V= \pi (9h^2 -12h + 4) *h$

$V= 4\pi (9h^2 -12h + 4)$
