3x*7x=21x
you add the exponents when you multiple so the exponents 2+5=7
8+3=11
your answer is 21x^7y^11
The area will be equal to Area = (28)(21) / 2 = 294 square inches.
<h3>What is the area?</h3>
To determine the area of a triangle, we calculate one half of the product of the base and the height of the triangle so we need data on its base and its height. We are given the following:
Hypotenuse = 7 + base = 14 + height
Perimeter = 84 inches
The perimeter of the triangle is equal to the sum of the three sides of the triangle which are the height, base and hypotenuse. So,
Perimeter = height + base + hypotenuse = 84
We let x = height and y = base. We calculate area as follows:
84 = x + y + (7 + y)
77 = x + 2y
x = 77 -2y
The Hypotenuse is related to the other sides by the Pythagorean theorem.
Hypotenuse^2 = (x^2 + y^2)
(14 + x)^2 = x^2 + y^2
(14 + (77-2y))^2 = (77-2y)^2 + y^2
(91-2y)^2 = (77-2y)^2 + y^2
Solving for y and x
y = 28
x = 21
Area = (28)(21) / 2 = 294 square inches

Answer:
y = -x+2
Step-by-step explanation:
using the point slope form of a line
y-y1 = m(x-x1)
y-2 = -1(x-0)
y-2 = -x
add 2 to each side
y-2+2 =-x
y = -x+2
this is in slope intercept form
