I got +/- 7 for this one.............
Answer:
1615 / 48
Step-by-step explanation:
So the mixed numbers as improper fractions is:
6 1/3 = 19 / 3
4 1/4 = 17 / 4
1 1/4 = 5 / 4
19 / 3 * 17 / 4 * 5 / 4 = 1615 / 48
It's kinda messy so it might be wrong.
Answer:
70°
Step-by-step explanation:
Size of angle a = (180°-40°) ÷ 2 (angle sum of triangle; base angles of isos triangle)
= 140° ÷ 2
= 70°
Answer: 4x^2 - 10x - 6
Step-by-step explanation:
You can use FOIL to do this. First terms, Outer terms, Inner terms, Last terms.
(x - 3)(4x + 2)
First terms: x * 4x = 4x^2
Outer terms: x * 2 = 2x
Inner terms: -3 * 4x = -12x
Last terms: -3 * 2 = -6
Now add these together:
4x^2 + 2x - 12x - 6 = 4x^2 - 10x - 6
