Simplifying

b2 + 12b + 35 = 0

Reorder the terms:

35 + 12b + b2 = 0

Solving

35 + 12b + b2 = 0

Solving for variable 'b'.

Factor a trinomial.

(7 + b)(5 + b) = 0

Subproblem 1

Set the factor '(7 + b)' equal to zero and attempt to solve:

Simplifying

7 + b = 0

Solving

7 + b = 0

Move all terms containing b to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + b = 0 + -7

Combine like terms: 7 + -7 = 0

0 + b = 0 + -7

b = 0 + -7

Combine like terms: 0 + -7 = -7

b = -7

A student said that x = 4 was not a solution to the question 3(x -6) = -8
Morgarella [4.7K]

Answer:

Step-by-step explanation:

3 (4 -6) = -8 is correct.  The next step is to combine 4 and -6, obtaining

3(-2)

and this 3(-2) should equal -6, which is not the same as -8.

3(4 - 6) = 12 - 18, which differs from the student's solution.  This is the reason for the wrong answer.

Two lines that intersect to form right angle are called
Sergio039 [100]

Answer:

perpendicular

Step-by-step explanation:

When 2 lines intersect at any point, not just in the middle of each (that has nothing to do with it), and they meet to form right angles, the lines are perpendicular to one another and their slopes are opposite reciprocals.
