Answer:A. x squared over 16 minus y squared over 4 ...
Step-by-step explanation:
if ya asking for simpliicatio
remember that
and
factor
X-4/2 = 10
x+-2=10
x-2=10
x-2+2=10+2
x=12
So first you want to start in the parentheses
x+5
so what you do is 2 times x which is 2x
2 times 5 which is ten
7x+10x <3x-14
-10× - 10x
-3x
Area of triangle = base x height x 1/2
Area of the triangle:
= 12 x 15 x 1/2
= 180 x 1/2
= 90 units^2
