Answer:
1.
2.
3.
Step-by-step explanation:
1. Both and 64 are perfect squares, meaning is twice the product of x and 8. Since all signs are positive, the equation would be: . Let and . Answer: or .
2. Since -3 is a factor of all 3 terms, factor out the -3 which makes, . K is also a common factor, so you would factor that out too, . Then simply, find the two factors whose product is -2 and whose sum is -5. Answer: .
3. By factoring , you would break the expressions in the group=. Then, factor out "x" from . Factor out "5" from = . Finally, factor out the common term "3x-1" =

Step-by-step explanation:
its a variable. this one represents x. a variable is something that represents an unknown value.
65% of 240
(65/100) * 240
0.65 * 240 Use your calculator.
= 156
Answer:
As you may know, the addition of all the interior angles of a triangle always adds up to 180°.
So if we know two angles of the triangle, A1, and A2, we can find the third angle as:
A1 + A2 + X = 180°
X = 180° - A1 - A2.
Se with only knowing two angles, we can find the third angle.
So aaa is a criteria equivalent to aa.
Now, the problem with this criteria is that also works for finding similar triangles (for example, an equilateral triangle of sides 10 and an equilateral triangle of sides 20 are similar, as the angles are the same, but are not congruent, as the length of the sides is different) and this happens because we only have information of the angles and know nothing of the sides.
