Expan and simplify the following expression:<br> 3(2a + 3)(2a - 1) - 4 (a^2 - 7)

Mekhanik [1.2K]

= 3(4a^2 + 4a - 3) - 4a^2 + 28
= 12a^2 + 12a - 9 - 4a^2 + 28
= 8a^2 + 12a + 19
= 4a(2a + 3) + 19

What is the equation for the circle with the center (11,6) and passes through the point (17,12)

MissTica

Answer:

The answer to your question is the letter D. (x - 11)² + (y - 6)² = 72

Step-by-step explanation:

Data

Equation = ?

Center = (11, 6)

Point = (17, 12)

Process

1.- Calculate the length of the radius using the distance between two points formula.

d = $\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}$

x1 = 11 y1 = 6

x2 = 17 y2 = 12

-Substitution

d = $\sqrt{(17 - 11)^{2}+ (12 - 6)^{2}}$

d = $\sqrt{6^{2} + 6^{2}}$

d = $\sqrt{36 + 36}$

d = $\sqrt{72}$

radius = $\sqrt{72}$

2.- Write the equation of the formula

(x - 11)² + (y - 6)² = ( $\sqrt{72}$ )²

Result

(x - 11)² + (y - 6)² = 72
