Answer: divide the big number by 2
Step-by-step explanation: dude it literally tells you the answer almost xD jsut divide the big number by 2
Hey!
The sum of four times a number and -2
Let us take the number as ' x '
( 4x - 2 )
Six times a number and 3
( 6x + 3 )
The sum = ( 4x - 2 ) + ( 6x + 3 )
Hope helps!
13 By the factor theorem, if the function is divisible by x - 3 then f(3) = 0. So we have:-
2(3)^3 + k(3)^2 + 7(3) - 3 = 0
9k = 3 - 21 - 54 = -72
k = -72/9 = -8 answer
14. Similarly , f(-4) = 0 , so we have:-
(-4)^3 + 9(-4)^2 + k(-4) - 12 = 0
-64 + 144 - 4k - 12 = 0
4k = -64 + 144 - 12 = 68
k = 68/4
k = 17 answer
Answer: B
Step-by-step explanation:
∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.
Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.
Answer:
Step-by-step explanation:
First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.
demoninator now doesn't change unless you're multiplying or dividing.
