What is 5r^2 = 80<br><br> It says solve each equation with the quadratic formula.

katovenus [111]

$5r^2 = 80 \ \ /:5\\ \\r^2=\frac{80}{5}\\ \\r^2=16\\ \\r^2-16=0\\ \\ r^2 - 4^2 =0 \\ \\(r-4)(r+4)=0$

$r-4=0 \ \ \vee \ \ r+4 =0 \\ \\r=4 \ \ \vee \ \ r = -4 \\ \\ \\ a^2-b^2 = (a- b)(a+b)$

Evaluate 2(x+ 1 - 3 when x = 6 O Ο Α. 11 OB. 5 O C. 8 ( D. 10

Mashutka [201]

$\implies {\blue {\boxed {\boxed {\purple {\sf {A. \:11}}}}}}$

$\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:\:EXPLANATION:}}}$

$2 \: ( \: x + 1 \: ) - 3$

Plugging in the value " $x\:=\:6$ " in the above expression, we have

$= 2 \: ( \: 6 + 1 \: ) - 3$

$= 2 \: ( \: 7 \: ) - 3$

$= 14 - 3$

$= 11$
