Answer:
x=10 and x=-6
Step-by-step explanation:
f(x)=(x-2)²-64 (Given)
0=(x-2)²-64 (Set equation equal to 0)
64=(x-2)² (Add 64 to both sides)
±8=x-2 (Take the square root of both sides)
Because there are two possible roots, make 2 equations to find both:
8=x-2 and -8=x-2
10=x and -6=x
6. Susana. Based on how they swam in their event, you can find out the possible time each person swam. Multiplying Tawni's time by four and Pepita's time by two and seeing which time is the least will give you this answer.
7. Ben can type 510 words in 10 minutes.
8. The extra fabric will cost $4.98.
6+2y, since the tree is already 6 feet, it grows 2 feet per year so you add 2 feet to the 6 feet every year
The answer is 90
because increased means times so 30 + 30 = 60 + 30 = 90
The answer is 171.25.
Hope this helped!
