HELP!! Find the product. (6a + b)2 1. 12a2 + ab + b2 2. 36a2 + ab + 36b2 3. 36a2 + 12ab + b2 4. 36a2 + b2

option 3

Step-by-step explanation:

Given

(6a + b)²

= (6a + b)(6a + b)

Each term in the second factor is multiplied by each term in the first factor, that is

6a(6a + b) + b(6a + b) ← distribute both parenthesis

= 36a² + 6ab + 6ab + b² ← collect like terms

= 36a² + 12ab + b²

XY = 2 units

Step-by-step explanation:

Given that :

ΔEFG ≅ ΔXYZ

Then, segments :

EF = XY, FG = YZ and EG = XZ

GIVEN THAT :

E (0, 0), F (0, 2), and G (3, 0)

We can find the distance between coordinates E (0, 0), F (0, 2) to get the measure of XY since they are both congruent.

EF = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

x1 = 0, y1= 0, x2 = 0, y2 = 2

EF = sqrt[(0 - 0)^2 + (2 - 0)^2]

EF = sqrt[ 0 + 4]

EF = 2

SINCE EF = XY

XY = 2 units
