Complete the square for x^2+12x-5.

Setler [38]

Answer:

$x^2+12x-5=(x+6)^2-41$

Step-by-step explanation:

The given expression is $x^2+12x-5$

Comparing to $ax^2+bx+c$ , we have $a=1,b=12,c=-5$

We add and subtract $(\frac{b}{2a})^2$

$x^2+12x+6^2-6^2-5$

This implies that:

$\boxed{x^2+6x+36}-36-5$

The expression in the rectangle is a perfect square

$(x+6)^2-41$

Therefore $x^2+12x-5=(x+6)^2-41$

Solve for x please help

34kurt

Answer:

x = 9

Step-by-step explanation:

By remote exterior angle theorem:

$(12x + 14)\degree = (1 + 5x) \degree+ 76 \degree \\ 12x + 14 = 1 + 5x + 76 \\ 12x - 5x = 77 - 14 \\ 7x = 63 \\x = \frac{63}{7} \\ \huge \red{ \boxed{ x = 9}}$

What is the length of BC¯¯¯¯¯ ? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vertex A lies above

OlgaM077 [116]

Answer: The length of BC is 22 units.

Explanation:

It is given that the Triangle ABC with horizontal side BC. Vertex A lies above side BC. Angle B and angle C are marked congruent. The length of side AC is labeled as 2x-24. The length of side AB is labeled as x-2. The length of side B C is labeled as x.

If two angles of a triangle are same it means the triangle is an isosceles triangle.

Since the angle B and C are congruent therefore the lines AB and AC are same.

$2x-24=x-2$
