Answer:
kevin is 6 years old
Step-by-step explanation:
Let Kevin's age now be a
Daniel's age now be b
Kevin is 3 years older than Daniel. -> a-3 = b
Two years ago, Kevin was 4 times as old as Daniel -> a-2 = 4(b-2) = 4b -8
-> a-3 -(a-2) = b - (4b-8)
-> - 1 = -3 b +8
-> -9 = -3b
-> b = 3
-> a = 6
Answer:
18x^2 + 12x - 6
Step-by-step explanation:
(6x - 2) (3x + 3 )
= 18x^2 + 18x -6x - 6
= 18x^2 +12x - 6
The answer is 9
One square is equal to one. for the rest just substitute the x and y for the given values
Answer:
m∠3 = 64°
Since angle 2 and 3 seem to be complementary angles, we know that the meaning of complementary angles is to add both angles to 90 degrees.
Subtract 90 by the known value to get the value of ∠3
90 - 26 = 64
