Answer:
B. AAS Congruence Theorem
Step-by-step explanation:
Previous steps showed congruence of a side of the designated triangle, and two angles that do not bracket that side. In short form, you have shown congruence of ...
Angle - Angle - Side
so the AAS congruence theorem applies.
A= 153.9 mm sq
Formula for area is pi times radius squared
Answer:
x=(0.45,-4.45)
Step-by-step explanation:
x²+4x=2
x²+4x+(2)²=2+(2)²
x²+(2)²=2+4
(x+2)²=6
√(x+2)²√6
x+2=√6
x=-2±√6
x=-2±2.45
x=(0.45,-4.45)
Simplifying the expression 8x +7 - 2x + y, by combining like terms is 6x + y + 7
<h3>How to simplify an expression?</h3>
The expression have to be simplified by combining the like terms.
Like terms are terms whose variables (and their exponents such as the 2 in y²) are the same.
Therefore,
8x +7 - 2x + y
The like terms are 8x and 2x . Therefore, lets combine it.
8x - 2x + y + 7
Therefore, the simplified expression is 6x + y + 7
