Sally spins a fair spinner numbered 1 - 5 and rolls a fair dice. What is the probability of spinning a multiple of 3 and rolling a factor of 10?

here

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
