Answer:
7x-2
Step-by-step explanation:
9(x+3)-(2x+5)
9x+3 -2x -5
7x-2
Answer:
[1] = 6
x = -3/2 is the root
Step-by-step explanation:
A perfect square trinomial is of the form ...
(a + b)² = a² +2ab +b²
You have ...
- a²=16w² ⇒ a = 4w
- b² = 36 ⇒ b = 6
- 2ab = 2(4w)(6) = 48w
Then the factorization is ...
16w² +48w +36 = (4w +6)²
This will be zero when x = -6/4 = -3/2.
Answer:
Gabby= 172.5 Jase= 137.5
Step-by-step explanation:
310-35= 275
275/2= 137.5 = Jase add 35 for Gabby
137.5+35=172.5

Answer:
30°,60°,90°
Step-by-step explanation:
<u>Let </u><u>:</u><u>-</u><u> </u>
<u>As </u><u>we</u><u> know</u><u> </u><u>:</u><u>-</u><u> </u>
<u>So </u><u>that</u><u> </u><u>,</u>
- x + 2x + 90 = 180
- 3x = 90
- x = 90/3
- x = 30
<u>Angles</u><u> </u><u>,</u>
