Answer:
Copy's area is 16 times bigger then triangle area.
Step-by-step explanation:
Given:
Area of copy = 72 unit²
Find:
How bigger copy compared to triangle
Computation:
Area of triangle = [1/2][base][height]
Area of triangle = [1/2][3][3]
Area of triangle = 4.5 unit²
So.
Area of copy / Area of triangle
72 / 4.5
16
So,
Copy's area is 16 times bigger then triangle area.
88.23%
Simply plug 15/17 into you calculator
and it will give you a decimal, in this case it should be .88235294...
simply move the decimal back to placements and you should have
88.235294... thats still a lot of numbers so just reduce it to 2 places after the decimal and add a percent sign
88.23%
and your done :) this works for any similar problems
I hope this helps
Complete the square: x^2 + 24x = 17
Identify the coefficient of x. It is 24. Take half of that coefficient: 24/2 = 12.
Now add the square of 12 to both sides of x^2 + 24x = 17
x^2 + 24x + 144 = 17 + 144
Write in factored form:
(x + 12)^2 = 161
Taking the square root of both sides:
x+12 = plus or minus
I think its letter D because x + 2y fits with the equation and there for -3
