Split the second term 7x^2 - 8x - 12 into two terms
7x^2 + 6x - 14x - 12
Factor out common terms in the first two terms, then in the last two terms
x(7x + 6) - 2(7x + 6)
Factor out the common term; 7x + 6
<u>(7x + 6)(x - 2) </u>
Answer:
Step-by-step explanation:
Distance formula: D = Square root (x^2-x^1)^2+(y^2-y^1)^2
H(-3,-4) Q(-8,1)
x1 y1. x2 y2
Plug in umbers
(-8+3)^2+(1+4)^2
(-5)^2 + (5)^2
25 + 25
Square root of 50 = 7.07106781187
7.1
Square root was always there I just don't know how to put it on a laptop.
Hope this helps!

The verbal expression is "<em>Four enn-cubed plus six</em>."
Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
