Step-by-step explanation:
it is a multiple of 21.
the highest common factor of 2 numbers is the longest combination of prime factors they have in common.
the prime factors of 21 are simply
3×7
if another number A shares this as the longest combination of prime factors, that means it contains 3×7 itself in its prime factors.
and that means this number A can only be a multiple of 3×7 (= 21), as other prime factors present would be the factor of 21.
Answer:
Step-by-step explanation:
-12 / 3 x (-8 + (-4)*2 -6) + 2
-12 / 3 x (-8 + 16 -6) + 2
-12 / 3 x (2) + 2
-4 x (2) + 2
-8 + 2
-6
Answer:
Y= 4x +y1-4x1
4 represent the slope m
+Y1 - 4x1 represent the intercept b
Step-by-step explanation:
Formula for the equation of the linear function
(Y-y1)/(x-x1) = m
We will transform it into the equation form
Y= mx + b
Where m = slope=4
b = intercept
(Y-y1)/(x-x1) = m
(Y-y1)/(x-x1) = 4
(Y-y1)= 4(x-x1)
Y-y1= 4x -4x1
Y= 4x +y1-4x1
4 represent the slope m
+Y1 - 4x1 represent the intercept b

Answer:
27
Step-by-step explanation:
Since it is addition to make the expression a perfect square, it would not be as direct
√9577 = 97.86214794
we round off to the nearest whole number, since we need a perfect square number
therefore it would be 98
98² = 9604, the perfect square number we'll get after adding to 9577
therefore amount needed to add= 9604-9577= 27
