Answer:
6 sides
Step-by-step explanation:
What I believe they are asking is to find which of those is the simplified quadratic formula. The quadratic formula is -b (plus or minus) (√b²-4ac) all divided by 2a.
This formula works when the equation is set up as ax²+bx+c
Answer:
Number line is shown in the attached file
Step-by-step explanation:
FIrst consider right side
It is an addition of two fractions.
SO let us make them with common denominator and add.
17/5= 17*4/4*5 = 68/20
and 7/20 = 7/20
Now these two have common denominator.
Adding we get 75/20 = 15/4 =3.75
Consider the number line with 0 in the middle and positive numbers on right side.
x<3.75 is the equivalent statement
Hence the left portion to the point 3.75 is the required graph.
Note that the point 3.75 will not be included as strictly less than

Answer:
common denominator of 1/a + 1/b is ab
however simplifying the complex fraction gives: (b-a)/(b +a)
Step-by-step explanation:
common denominator of 1/a + 1/b
should be the product of the denominators
a*b
so 1/a + 1/b = (b + a)/ab
ao
( 1/a - 1/b) divided by (1/a + 1/b) = (b - a)/(ab) divided by (b+a)/ab
Answer:
The smallest side is 7inches
Step-by-step explanation:
Let the shorter side be y.
The medium side is 4 more than the short side i.e
Meduim side = 4 + y
The longest side is 5 times the length of the shortest side i.e
Logest side = 5y.
Perimeter of the triangle = 53 inches
But the perimeter of a triangle is the Sum of all sides i.e
P = small + medium + large
53 = y + (4+y) + 5y
53 = y + 4 + y + 5y
Collect like terms
53 — 4 = 7y
49 = 7y
Divide both side by 7
y = 49/7
y = 7inches
Therefore the smallest side is 7inches
