1. Use the formula to evaluate the series -3 + 6 - 12 + 24 - ...-a. Sn =
al(1-7)
1-1
In the formula for a finite series, a, is the first term, r is the common ratio, and n is the number of terms.

Pls urgent max amount of points will be given and pls do not answer if unsure or you will be reported by me and brainliest answer gets the brainliest .. thing so yeh

Its due ! write an equation in which the quadratic expression 2x^2-2x 12 equals 0. show the expression in factored form and explain what your solutions mean for the equation. show your work.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
