Since it's isosceles, ∠ABC = (180-30) / 2 = 75

I hope this helps you

ACB=ABC=180-30/2=75

angle C=angle B

A+B+C=180

2B+30=180

OR

2C+30=180

B=C=75

What is the product in the simplest form? State any restrictions on the variable.

Veronika [31]

Answer:

see explanation

Step-by-step explanation:

Factor the numerators/ denominators where possible

x² + 7x + 10 = (x+ 2)(x + 5)

x² - 3x - 18 = (x - 6)(x + 3)

x² + x - 2 = (x + 2)(x - 1)

Hence

= $\frac{(x+2)(x+5)}{x+3}$ × $\frac{(x-6)(x+3)}{(x+2)(x-1)}$

Cancel the factors (x + 2) and (x + 3) on numerator/denominator

= $\frac{(x+5)(x-6)}{x-1}$ ← in simplest form

The denominator of the product cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.

solve x - 1 = 0 ⇒ x = 1 ← restricted value

Please help me with problem 2 of Inequalities in Two Variables

trapecia [35]

With inequalities,

< means less than

> means greater than.

Both are represented by a dotted line.

≤ means less than or equal

≥ means greater than or equal,

Both are represented by a solid line.

To construct the inequality x<2 we would switch the < to an equal sign, and construct the equality, namely x=2, which is a vertical line passing through (2,0).

From the previous comments, we know that x<2 is a dotted line.

Now we have to decide the inequality applies to which side of the line.

One way is to take some test points, e.g. the origin (0,0) where x=0.

Since x=0 is less than two, we know that (0,0) satisfies the inequality, so the area to the left of the vertical line (x=2) satisfies the inequality.

Hence the proper graph would show the left side shaded, but at x=2, the vertical line should be dotted.

An even simpler rule to find the region is to see that "x < something" is to the left, and "x > something" is to the right of a vertical or a slanted line.
