Step-by-step explanation:
a · b = (4)(3) + (5)(6)
a · b = 12 + 30
a · b = 42
Answer:
58
Step-by-step explanation:
Angle NPO is a right angle, then the angle 32 is equal to angle PNO, so x = 90 - 32 = 58.
Supplementary angles are angles that add up to 180 degrees.
m<3 + m<4 = 180 degrees
116 + m<4 = 180 degrees.
Subtract 116 from both sides.
m<4 = 64 degrees
Answer:
2x2
−x+3
Step-by-step explanation:
Answer:
infinite solutions
Step-by-step explanation:
The coefficient of x in the first equation is 3 times the coefficient of x in the second equation. This means we can eliminate x by subtracting 3 times the second equation from the first:
(15x +12y) -3(5x +4y) = (18) -3(6)
0 = 0 . . . . . simplify (true for all values of x or y)
The system of equations has an infinite number of solutions.
