Answer:
-3
4
Step-by-step explanation:
You need to take something called the dot product
I will get you started.
x^2+4x-4 = 8
x^2 + 4x - 4 - 8 = 0
x^2 + 4x - 12 = 0
You must now use the quadratic formula.
In the formula, a = 1, b = 4, and c = -12.
Take it from here.
Zoe will need to buy 48 beads.
3 + 1 + 2 = 6.
6 x 8 = 48.
Hope this helps!!!:)
Answer: 502.65
Step-by-step explanation: A= 2πrh + 2πr^ this is the formula for solving the surface area so now you must substitute
2·π·5·11+2·π·5^
6.28 · 55 + 2 π · 25
add and you will get 502.65 hope this helps mark me brainliest if it did
