Answer:
A. 15.
Step-by-step explanation:
9^2 + 12^2
= 81 + 144
= 225.
Taking the square root: we get 15.
83 + 113 + 111 = 307
360 - 307 = 53
answer: 53°
hope this helps :)
Well you could factor out the 2 in the equation
6=3*2
10=5*2
4=2*2
so
6x^2-10x+4=2(3x^2-5x+2) so
factor 3x^2-5x+2 and get
(x-1)(3x-2)=0
so xy=0 then x and/or y=0 so
x-1=0
x=1
3x-2=0
3x=2
x=2/3
x=1 or 2/3

Answer:
(C) 64.26 m²
Step-by-step explanation:
You know the area is almost, but not quite, the area of two squares that are 6 m on a side. The area of one of those squares is (6 m)² = 36 m². The area of two of them is 2×36 m² = 72 m².
Since the area is larger than 36 m² and smaller than 72 m², there is only one answer choice that makes any sense:
64.26 m²

That value is obtained using 3.14 for pi.
