Answer:
13
Step-by-step explanation:
All the lengths in triangle ADE are twice those in similar triangle ABC. So ...
x-1 = 2(6)
x = 13
<em>Answer:</em>
<em>2 whole 1/4</em>
<em>Step-by-step explanation:</em>
<em>When forming a perfect square trinomial you need to "complete the square".
</em>
<em>All of the steps to completing the square when solving an equation:
</em>
<em>1. The leading coefficient must be 1. </em>
<em>2. Divide b by 2.
</em>
<em>3. Square (b/2)
</em>
<em>4. Add (b/2)^2 to both sides to keep the polynomial balanced.
</em>
<em>5. You can now write the perfect square trinomial and solve.
</em>

x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4
Answer:
Step-by-step explanation:
-16 + 12s - 22t + 6u
Here are the pairs:
(from the left)
First group: 3rd graph, y = x - 2, table g
Second group: 2nd graph, y = 2x, table b
Third group: 1st graph, y = x + 2, table m
Use distributive property
x^2+x-14+(-x+22)i
