15 and 20, because 15+20=35 and 15×20=300
Explanation:
Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.
So far... we know that:
Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.
Answer:
∠2 = 40
∠11 = 60
Subtracting 8 from both sides of the equation gives
x^2 + 4x - 12 = 0
(x + 6)(x - 2)= 0
x = -6, 2 answer
Answer:
Step-by-step explanation:
g^3
f / g^3
Answer:
9
Step-by-step explanation:
Let the number be n.
Then: 4n + 15 = 6n - 3
Subtract 4n from both sides, obtaining: 15 = 2n - 3
Now add 3 to both sides, obtaining 18 = 2n. Then n = 9.
