The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation <span>9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
</span>using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +-
/ 2(9)
Step-by-step explanation:
Area of the circle = pi×r²
= 22/7 × 6 × 6
= 113.14 unit²
180 - 63 - 22 = 95 would be the length of the third angle
Answer:
x = -2

Answer:
The first student ate 1.35lbs. The second student ate .63lbs.
Step-by-step explanation:
3/20=.15, plus another 1.2=1.35
3/5=.60, plus another .03=.63
In total, both students ate 1.98lbs of candies.
