Need help ASAP!!

1. (-5)(6)(-7) =...

2. On Monday Luke’s business lost $15. On Tuesday it made $8. On Wednesday it broke even. What is the total profit of loss during those 3 days?

3. If a^2>20 then which of the following could be a value of a? Circle all that apply.
A. 6 b. 3 c. (-8) d. 2

4. Bees are leaving their hive at a rate of 10 per hour and they are reentering the hive at a rate of 6 per hour. If the hive starts with 100 bees, how long will it take before the hive is empty?

Thanks in advance! Have a wonderful day! Please provide steps if possible =)

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

Heptagon is the correct ans
