SCORPION-xisa [38]3 years ago

Answer:

(y + 14)(y - 14)

Step-by-step explanation:

A difference of squares has the general form

a³ - b² and factors as

(a + b)(a - b)

Given

y² - 196

y² = (y)² ⇒ a = y and 196 = 14² ⇒ b = 14

y² - 196

= y² - 14² = (y + 14)(y - 14) ← difference of squares

Please help me on this!!
Gekata [30.6K]
Hi there!

Let's solve this problem step by step!
The sum of the angles measures 360°, which is given in the question.

We can also express the sum of the angles as a sum of variables. To do this we must add all the variables a.
a + a + 2a + 2a =

Collect terms.
6a

When we have this expression and the sum of the angles, we can set up and solve an equation.
6a = 360

Divide both sides by 6.
a = \frac{360}{6} = 60

Therefore a = 60°
~ Hope this helps you!

I don’t know what to do
Amanda [17]

BC = 19.1-10.4 = 8.7

19) AB = BC = 8.7

20) CG = 30.6 -8.7 =21.9

21) AG = 8.7 +30.6 = 39.3

22) FG = DG (DG = 30.6-10.4-8.7) = 11.5

23) EH = 8.7 + 11.5 +8.7 = 28.9

24) EJ = 8.7 + 11.5 + 21.3 = 41.5
