b = (a - 3)²
Our aim is to get <u><em>a</em></u> to be alone
1) First we get rid of what's in the brackets. So we subtracts each side by 3. Of course, the opposite of subtracting is adding:
b+3 = a²
2) Now we get rid of the squared in a. Opposite of squaring is square rooting.
3) There we have it. a is now by itself. We can test if we're right by substituting.
Lets make a=2
b=(a-3)²
b= (2-3)²
b= 1

Answer:
5 is the correct answer
Step-by-step explanation:
Answer:
Six cases are enough to construct more than one isosceles triangle
Step-by-step explanation:
An Isosceles triangle is a triangle in which at least two of it's sides are congruent.
If two of the three sides of a triangle are congruent, but the third side is of a different length, the triangle is isosceles.
If all three sides of the triangle are congruent, even though this is an equilateral triangle, it satisfies the condition of an isosceles, and it is ok to still it isosceles.
Julius might decide to split information for a better explanation, it doesn't matter the number of cases he has, but six cases should be enough to draw an isosceles triangle.
Answer:
$12,000,000
Step-by-step explanation:
To find her commission, create a proportion.
To solve use cross multiplication.
40(x) = 100(480000)
40x = 48000000
x= 12,000,000
Answer:
Two lines, both in the same plane, that never intersect are called parallel lines. Parallel lines remain the same distance apart at all times. The symbol // is used to denote parallel lines.
how to prove that two lines are equal: If two lines are cut by a transversal and the alternate exterior angles are equal, then the two lines are parallel. Angles can be equal or congruent; you can replace the word "equal" in both theorems with "congruent" without affecting the theorem. So if ∠B and ∠L are equal (or congruent), the lines are parallel. therefore the answer is E. The two lines are everywhere equidistant.
