The answer is A, you can tell because if you multiply 4 by the numbers inside the parentheses you’ll get =12+24..hope that helped :)
Answer:
Step-by-step explanation:
x² + 6x + 1 = 0
a = 1 , b = 6 , c = 1
Answer:
using Pythagoras rule, 16^2 -7^2 =a^2
so 256-49 = 297.
√207 =14.38 to the nearest tenth of an inch is 14inch.which is your answer
25 goes into 200 exactly 8 times.
Answer:
r = -1 or r = 13/3
Step-by-step explanation:
Solve for r over the real numbers:
abs(10 - 6 r) = 16
Split the equation into two possible cases:
10 - 6 r = 16 or 10 - 6 r = -16
Subtract 10 from both sides:
-6 r = 6 or 10 - 6 r = -16
Divide both sides by -6:
r = -1 or 10 - 6 r = -16
Subtract 10 from both sides:
r = -1 or -6 r = -26
Divide both sides by -6:
Answer: r = -1 or r = 13/3
