The formula for the discriminant is the square root of b^2 - 4ac

8x^2+18x-5= 0

a = 8, b=18, c= -5

Square root of 324 +160

Square root of 484 = 22                The discriminant is 22

What is the lcm of 6and 15
Maurinko [17]
LCM stands for least common multiple. We are being asked to find the lowest multiple that 6 and 15 have in common.

Multiples of a number (n) are integers that are the product of n and another number. Let's list the multiples of both 6 and 15:

6: 6, 12, 18, 24, 30, 36

15: 15, 30, 45, 60, 75, 90

The LCM of 6 and 15 is 30.

Perimeter of an isosceles triangle is 35 cm if the length of a the congruent sides is 3 times the length of the third side what
Dimas [21]

Let the length of the shortest side = x

The two longer sides that are equal = 3x

The are two equal longer sides, so their total is 3x + 3x = 6x

3x+ 3x + x= 35  Collect like terms on the left

7x = 35               Divide by 7  on both sides

x = 35/7

x = 5

Answer

Two long sides -- 15 cm each

Shortest side -- 5 cm

What is the equation of y=2x-6 in standard form?
prisoha [69]

Answer:

2x - y = 6

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y = 2x - 6 ( add 6 to both sides )

y + 6 = 2x ( subtract y from both sides )

6 = 2x - y, that is

2x - y = 6 ← in standard form
