Answer: one dollar and 56 cents
Step-by-step explanation:
11 cents= one peny is one cent
6 dimes= 60 cents, one dime is 10 cents
3 qurters= 75 cents, one quaters is 25 cents
2 nicales= 10 cents, one nicale is 5 cents
one dollar is 100 cents
X^2+3x=24, halve the linear coefficient, square it, and add it to both sides
In this case (3/2)^2=2.25
x^2+3x+2.25=26.25 now the left side is a perfect square...
(x+1.5)^2=26.25 take the square root of both sides
x+1.5=±√26.25 subtract 1.5 from both sides
x=-1.5±√26.25
x=-1.5-√26.25 and -1.5+√26.25
x≈ -6.62 and 3.62
Answer:
Correct choice is C). mn=ac
Step-by-step explanation:
Given statement is that the first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.
We know that when we factor polynomial of type 
,product of both numbers m and n must be same as product of a and c.
Hence correct choice is C). mn=ac
Sqrt -13 = sqrt13 i
sqrt -26 = sqrt2 * sqrt13i
sqrt-13 * sqrt -26 = sqrt2 * 13* i^2 = -13 sqrt2 (because i^2 = -1)
answer is -13 sqrt2
