Answer:

x = -2 or x = -3

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + 5 x + 6 = 0

The left hand side factors into a product with two terms:

(x + 2) (x + 3) = 0

Split into two equations:

x + 2 = 0 or x + 3 = 0

Subtract 2 from both sides:

x = -2 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = -2 or x = -3

Can someone help me find the area of this figure ? Thanks!

nordsb [41]

Answer:

25 units²

Step-by-step explanation:

We know that:

Some squares are 100% shaded, and some are half shaded.
Half shaded squares: 10 squares
100% shaded: 20 squares
Area of figure = Area of half shaded + Area of 100% shaded

Solution:

Area of figure = Area of half shaded + Area of 100% shaded
=> Area of figure = (10 x 1/2) + 20
=> Area of figure = 5 + 20
=> Area of figure = 25 units²

Hence, the area of the figure is 25 units².

Which two lines are parallel? Which two lines are perpendicular?

lana66690 [7]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

All the equations given are in slope- intercept form

y = 2x + 1 → with m = 2

y = $\frac{1}{2}$ x - 4 → with m = $\frac{1}{2}$

y = x + 1 → with m = 1

y = - $\frac{1}{x}$ x - 3 → with m = - $\frac{1}{2}$

y = 10 + x → y = x + 10 → with m = 1

Thus

y = x + 1 and y = 10 + x are Parallel since both have m = 1

y = 2x + 1 and y = - $\frac{1}{2}$ x - 3 are Perpendicular since 2 × - $\frac{1}{2}$ = - 1
