Classify the following triangle. check all that apply.

Scalene and Acute

Step-by-step explanation:

Since none of the sides have the same length: scalene

Isosceles ( 2 sides same length)  False

Equilateral( 3 sides same length) False

Acute: all angles less than 90 degrees:  True

Right:  one angle equal to 90 degree:  False

Obtuse:  One angle greater than 90 degrees:  False

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is
