Hello!
Let’s do it step-by-step, shall we? Don’t worry! These problems can be a bit tricky but you’ll get it in no time! It’s really simple.
So, we have (-7)(-5)
This means that the problem will be multiplied because of the parentheses. They substitute the multiplication sign.
So, we have -7 (multiplied by) -5= 35
So your answer would be 35. Hope this helps :) and good luck!
Answer:
45,54,63,72,81 for the 5 multiples of 9
63 is the least common multiple of 7 and 9
Step-by-step explanation:
(900,000)+(0)+(8,000)+(100)+(0)+(9)
Glad I could help u just need to write the zeros on which the number is in like 9 was in the hundred thousand place and hundred thousand has 6 zeros so we put the nine and add the 6 zeros. Have A Good day
Answer:
k = ± 4
Step-by-step explanation:
Given
x² - kx + 4 = 0 ← in standard form
with a = 1, b = - k, c = 4
The equation has equal roots, thus the discriminant
b² - 4ac = 0, that is
(- k)² - (4 × 1 × 4) = 0
k² - 16 = 0 ( add 16 to both sides )
k² = 16 ( take the square root of both sides )
k = ± 
= ± 4
