Solve 2x2 + 12x − 14 = 0 by completing the square, options: A. 2(x + 6)2 = 26; x = −6 + square root 13, x = −6 − square root 13 B. 2(x + 6)2 = 20; x = −6 + square root 20, x = −6 − square root 20 C. 2(x + 3)2 = 32; x = 1, x = −7 D. 2(x + 3)2 = 32; x = 13, x = 19

Answers

I just solved this one
anothe way is undistribute the 2 first and move -14 to side
2(x^2+6x)-14=0
comlete the squer inside and add negative
2(x^2+6x+9-9)-14=0
factor perfect square
2((x+3)^2-9)-14=0
distribute
2(x+3)^2-18-14=0
2(x+3)^2-32=0
add 32 both sides
2(x+3)^2=32
divide 2
(x+3)^2=16
sqrt both sides
x+3=+/-4
minus 3
x=-4-3 or 4-3
x=1 or -7

answer is C

Answer:

the answer is c: 2(x + 3)2 = 32; x = 1, x = −7

Taylor says that 40 percent of 50 is the same amount as 50 percent of 40 is she correct

Answers

If you would like to know if Taylor is correct, you can calculate this using the following steps:

40% of 50 = 40% * 50 = 40/100 * 50 = 20
50% of 40 = 50% * 40 = 50/100 * 40 = 20

Result: Taylor is correct, because 40% of 50 equals to 50% of 40.

She is correct 40% is 50 because the answer is 125

Toni Mahoney is using Biscuit Betty's recipe that requires 5 1/3 pounds of flour to make biscuits for her brunch. Suddenly, Toni learns that 4 times as many people are coming to her bunch than originally planned. How much flour will Toni need to make her biscuits? Explain how tou got your answer.

Answers

21 1/3 pounds of flour. We know it takes 5 1/3 pounds of flour for one brunch. So, if there are 4 times as many people, we have to multiply 5 1/3 by 4. After you do 5 1/3 times 4 you will get 21 1/3 pounds of flour.
