Answer: The answer is 13x+y
Step-by-step explanation:
Answer:
Option A) 1
Step-by-step explanation:
we know that
The solution of the nonlinear system of equations is the intersection point both graphs
In this problem the intersection point is (-2,-1)
therefore
The system of equations has only one solution
Answer:
Step-by-step explanation:
Given : length = , width =
Perimeter of rectangle = 2 ( length + width)
Then, Perimeter of given rectangle =
Hence, the correct expression for perimeter =
1. 12a²b² + -7a²b² + 9a²b²
= 14a²b² (the terms a²b² are like terms so don't look at them, just add 12 + (-7) + 9.
= 14 (ab)² (you can write like this too because both a & b are squared).
2. y² - (-5y²)
= 6y² (subtract -5 from 1, y² is the like term).
m∠ABD = 45° and m∠DBC = 45°
<u>Step-by-step explanation:</u>
Non-overlapping angles are the adjacent angles which do not overlap and they have the common vertex and also they have the common side.
Here ABC is right angle and it is decomposed to two non- overlapping angles ABD and DBC which has the common vertex B and the common line BD.
So the two non overlapping angles are:
m∠ABD = 45°
m∠DBC = 45°
or the angles may be
m∠ABD = 35°
m∠DBC = 55°
So it was found.
