The x coordinate stays the same but y coordinate changes sign so it will be a reflection in the x-axis.
Answer:
I would choose A
Step-by-step explanation:
I chose A because it's an hypotenuse because of the different sides
Answer:
you need to put the table
Step-by-step explanation:
If the perimeter is 200 ft and the area is 2100 square feet...
P = 2l + 2w
A = l * w
The dimensions would be 30 ft by 70 ft.
The area of a triangle can be calculated using the formula
1/2 (base) (height)
Let's substitute our known values, letting x represent the value of the height of the triangle.
16 = 1/2* x* 2x
Let's Simplify!
16 = x^2
Finally, lets take the square root of both sides, to get rid of the exponent on the right side of the equation.
x= positive OR negative 4.
However, because x is equal to the height, we know that it can't be negative, so we know that it is positive 4.
The height of the triangle = 4 inches
The base of the triangle = 2h = 8 inches
