Answer:
Step-by-step explanation:
Area of the green shaded part
= Area of square with side 6 cm - Area of circle with radius (6/2=3) 3 cm.
Answer:
x=(-13/5), y=(-6/5)
Step-by-step explanation:
I will do step by step since I dont see a picture.
when you add them it gets rid of the y,
5x=-13
divide out the 5
x=(-13/5)
plug this into the first equation
2(-13/5)-y=-4
-5.2-y=-4
add 5.2 to each side
-y=1.2
divide out the negative
y=-1.2 or (-6/5)
An easy way to think of this when you solve this, is to remember that all the angles in a triangle add up to 180 degrees. Therefore, the equation would be
(3x + 10) + (2x + 10) + 45 = 180. By the way, since the angles D and B are across from each other they are congruent. Now, let’s start solving it:
(3x + 10) + (2x + 10) + 45 = 180
(5x + 20) + 45 = 180
5x + 65 = 180
5x = 115
x = 23
Answer:
The expanded form: y=(2x-3)(x+3)
The simplified form: 2x^2+3x-9
