If fe =12 and. De= 5 df would be 17
X^2/a^2+y^2/b^2=1
or
x^2/900 + y^2/169 = 1 x^2/1467^2 + y^2/736^2= 1 x^2/736^2 + y^2/1467 = 1 x^2/169 + y^2/900 = 1
Answer:
1/4 or 0.25
Explanation: Convert the mixed numbers to improper fractions, then find the LCD and combine.
Isolate x. First, add 2/5 to both sides
x - 2/5 (+2/5) = 1/3 (+2/5)
x = 1/3 + 2/5
to simplify, find common denominators (15 in this case). Multiply the same number to both the denominator and numerator
(1/3)(5/5) = 5/15
(2/5)(3/3) = 6/15
x = 5/15 + 6/15
Simplify
x = 11/15
11/15 is your answer for x
hope this helps
Answer:
9x^2+42x+45
Step-by-step explanation:
Foil (3x+5)(3x+9) by taking the numbers in the left parenthesis and multiplying it by the numbers on the right. So 3x(3x), then 3x(9), then 5(3x) and 5(9). Now we have 9x^2 + 27x+15x+45, simplify to get 9x^2+42x+45.
