Answer:
126
Step-by-step explanation:
Let x be the missing length
The triangles are similar:
● UE/140 = 45/x
From the graph we deduce that:
● UE = 140 - 90 = 50
Replace UE by its value
● 50/ 140 = 45/x
Switch x and 50
● x / 140 = 45/50
45/50 is 9/10 wich is 0.9
● x/140 = 0.9
Multiply 0.9 by 140
● x = 140 × 0.9
● x = 126
They expect a good test grade A+
The sum of three primes is 18 so they must all be smaller than 18 as well.
Primes less than 18=2,3,5,7,11,13,17
2,3, and 13
2,5, and 11
There are two solutions...
Answer:
9x^2 25x+14
Step-by-step explanation:
using FOIL:
(x+2)(9x+7)
9x^2 +7x + 18x +14
9x^2 25x+14
