The area A of a triangle with base b and height h is given by A = = bh. Find the area when b = 18 m (meters) and h = 30 m.

Pie

Answer:

$Area = 270m^2$

Step-by-step explanation:

Given

$A = \frac{1}{2}bh$

$b = 18m$

$h = 30m$

Required

Solve for A

Simply substitute 18 for b and 30 for h

$A = \frac{1}{2}bh$

$A = \frac{1}{2} * 18 * 30$

$A = 270$

Hence:

The area is

$Area = 270m^2$

Which statement correctly explains how Dana can solve the following system of linear equations for x using the elimination metho

Vanyuwa [196]

1. The correct statement is the first one, which is: Add the two equations, solve for y, and then substitute –1 for y to find x.

2. Therefore, you have the following system of equations:

4x+8y=20
-4x+2y= -30

3. When you add the two equations, and clear the variable "y", you obtain:

10y=-10
y=-1

4. Now, you must substitute -1 for y (y=-1) to find x, as below:

4x+8y=20
4x+8(-1)=20
4x-8=20
4x=20+8
4x=28
x=28/4
x=7
