B+B=2
assuming that B is 1 I will say that 4 is C.
4+1*2= 10 is your answer.
Answer:
The variables change
Step-by-step explanation:
Since we can't subtract c from -b we multiply both variables by a because the question is telling us to subtract b and c then multiply the awnser by a, but we don't know what b and c is so we just multiply b and c by a. In the end we get ab-ac
Answer:
ME! but that's not a real question on top right
Answer: 19/40
Step-by-step explanation:
First Write 0.475 as 0.4751Multiply both numerator and denominator by 10 for every number after the decimal point0.475 × 10001 × 1000 = 4751000. Reducing the fraction gives The answer
Step-by-step explanation:
well,
(y - 7)² = (y - 7)(y - 7)
remember how to multiply 2 expressions ?
you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).
so, when we do the multiplication, we get
(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =
= y² - 14y + 49
and that is clearly different to y² - 49
FYI
y² - 49 is the result of
(y - 7)(y + 7)
because
y×y + 7×y - 7×y + (-7)(7) = y² - 49
