Mutiply them all out, you'll get quadratic equations. Replace x's with numbers and then you'll be able to draw the graphs
Answer:
1.9( j + 8 + j)
2. 9(4 j) + 9 (8 + j)
2. 45 j + 72
Step-by-step explanation:
1.nine times, open parentheses four times j plus eight plus j
2. 9(5 j + 8)=
Sarah had a total amount of 45 teeth meaning that her neighbor gave Sarah $225.
Answer:
x= 5.55 and 0.45
Step-by-step explanation:
Quadratic Equation = (-b±√b²-4(a)(c))÷2(a)
Get equation = to 0 by subtracting the 3 on the right side of the = sign
2x² - 12x + 5
Identify the variables
a=2
b=-12
c=5
Put them into the quadratic equation
(-(-12)± √-12² - 4(2)(5))÷2(2)
Simplify
(12 ±√144 - 40)÷4
(12±√104)÷4
Now split into 2 equations (one with addition one with subtraction) because of the ± then continue simplifying
(12 - √104)÷4 (12 + √104)÷4
(12 - 10.198039)/4 (12 + 10.198039)/4
5.54950975 0.45049025
Round
5.55 0.45
