PLZZZZZZZZZZZ HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Luda [366]

Answer:

Step-by-step explanation:

Your first step is to figure out which variable you want to cancel out.

Luckily, all these problems have x or y already set up to eliminate.

You can find these variables because they are opposite signs of each other, such as -x and x

Add the y's together and the #'s on the other side together, then solve to find the 2nd variable. Once you find one, you can plug that answer into the easier of the two equations and solve for the other variable.

The vertices of a triangle are A (0,0), B (3, 4) and C (-4,5). Find the length of each side.

Sphinxa [80]

Answer:

AB = 5 units

BC = 5 $\sqrt{2}$ units

AC = $\sqrt{41}$ or about 6.4 units

Step-by-step explanation:

distance formula: square root of the sum of the difference of the y-values and the difference of the x-values

ex, dAB = √(4-0)² + (3-0)²

= √16 + 9

= √25

= 5

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and

maxonik [38]

Answer:

$10cm^2$

Step-by-step explanation:

We are given that

Two parallel sides of trapezoid are

$a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm$

$b=3\frac{1}{2}=3+0.5=3.5 cm$

Height of trapezoid, h=4 cm

We have to find the area of the trapezoid.

We know that

Area of trapezoid= $\frac{1}{2}(a+b)h$

Where a and b are two parallel sides

h=Height of trapezoid

Using the formula

Area of trapezoid= $\frac{1}{2}(1.5+3.5)\times 2$

Area of trapezoid= $10cm^2$
