Answer:
option 4
Step-by-step explanation:
g(x) = x² + 4x + 4
= x² + 2 * x * 2 + 2² {Compare with identity a²+ 2ab +b² = (a +b)²}
= (x + 2)²
Answer:
convert the task into ratios
(1) if $24 = 4 walks
how many $ for a walk
= (24/4) $/walk
= $6 per walk
•the first one is correct
•the second is wrong, cause it interprete $12/3 walks, which is rationalized to $3 per walk
•the third one is correct, cause it can also be rationalized ($30/5walks) to $6 per walk.
also, rationalizing this would equate to 3 miles per hour (6miles/2hrs)
• one is wrong cause it's 4 miles per hour
•two is correct, it's saying 3 miles per hour (12/4)
• third, likewise is correct 3 miles per hour (9/3) miles/hrs
Its an exponential growth
Hello!
Let's use 'x' to represent the cost of the burger, and 'y' to represent the cost of the hotdog.
2x + y = 482
× + 2y = 370
2x + 47 = 740
-3y = -258
y = 86 cents
2x + 86 = 482
2x = 396
x = 198
A burger costs $1.98 and a hot dog costs $.86
I hope this didn't confuse you, I'm not very good at explaining!
Answer:
<h3>
It's about 365 cm²</h3>
Step-by-step explanation:
2×πr² + 2πr×h =
= 2×π×4² + 2π×4×10.5 =
= 32π + 84π =
= 116π ≈
≈ 364.42 cm²
