Since you’re already given one of the sides of the triangles as well as the triangle’s hypotenuse, you’ll want to find the third side to find the area.

To find the third side length, we’ll use the Pythagorean Theorem:

a^2 + b^2 = c^2

“a” and “b” can be used interchangeably, so we can substitute the known side length of 7 cm into “a”. 25 cm substitutes for “c” since it’s the hypotenuse.

(25)^2 - (7)^2 = c^2

c = 24

Area of triangle = (1/2)bh, where “b” and “h” are interchangeable.

Area of triangle = (1/2)(24)(7) = 84 cm^2

Convert 1 3/5 to an improper fraction;

-1 × 5 + 3/5 ÷ -2/3

Simplify 1 × 5 to 5

-5 + 3/5 ÷ -2/3

Simplify 5 + 3 to 8

-8/5 ÷ -2/3

Use this rule: a ÷ b/c = a × c/b

-8/5 × 3/-2

Use this rule; a/b × c/d = ac/bd

-8 × 3/5 × - 2

Simplify 8 × 3 to 24

Example 2
Arada [10]

Answer:

y=x-2

Step-by-step explanation:

If you have drawn the graph of y = x^2 - 3x + 1.

To determine the equation of the line which  should be drawn to solve the equation:  x² - 4x +3=0

Simply carry out the subtraction: x^2 - 3x + 1 -(x^2 - 4x +3)

\implies x^2 -3x + 1-x^2 + 4x -3 \\= x^2 - x^2+ 4x - 3x-3  + 1\\=x-2

The equation of the line which should be drawn is: y=x-2

What this means is simply:

If

y = x^2 - 3x + 1$ and $y=x-2,$ then:\\x^2 - 3x + 1=x-2\\x^2 - 3x + 1-x+2=0\\x^2 - 4x + 3=0

So 6.5 inches long in scale, but every 2 in is 5 yards.
Divide 6.5 by 2. This gives you 3.25. Then multiply by 5 to get yards.
It’s 16.25 yards long.
