25x² - 36
25x² + 30x - 30x - 36
5x(5x) + 5x(6) - 6(5x) - 6(6)
5x(5x + 6) - 6(5x + 6)
(5x - 6)(5x + 6)
The answer is C.
Answer:
x=4.5 and y= -6
Step-by-step explanation:
2x+5y= -21
-2x+3y= -27
add the two equations: 8y= -48
y=-48/8= -6
sub for y in 2x+5y= -21
2x + 5(-6)=-21, 2x-30= -21
2x= -21+30= 9
x= 9/2=4.5
It’s gunna be 60.2 I believe
<span>Each Exterior Angle = (360 degrees) ÷ (Number of Sides)
</span>
A pentagon has 5 sides so
<span>Each Exterior Angle = 360 / 5
</span>
Each Exterior Angle =72
If the exterior angle = 2x and the angle = 72 degrees then
2x = 72 and
x = 36

Triangles can be congruent if they have the exact same length of 3 sides and same 3 angles.
If you do not know all 3 sides and 3 angles, you can postulate using the SSS,SAS,AAS,ASA , which is just
Side Side Side, Side Angle Side, Angle Angle Side...
Side means 1 Same length side, Angle means 1 Same corresponding angle.
e.g. ASA means 2 Same corresponding angle and 1 same corresponding side length.
