Hi Brainiac
4x-5=2(2x+1)
Distribute
4x-5= (2)(2x)+(2)(1)
4x-5=4x+2
Subtract 4x
4x-5-4x= 4x+2-4x
-5=2
Add 5
-5+5=2+5
0=7
There are no solutions
I hope that's help:0

Answer:
6a3 + 22a2 + 14a - 10
Step-by-step explanation:
(3a + 5) x (2a^2 + 4a - 2)
= 3a(2a^2 + 4a - 2) + 5(2a^2 + 4a - 2)
= 6a^3 + 12a^2 - 6a + 10a^2 + 20a - 10
= 6a^3 + 22a^2 + 14a - 10

Step-by-step explanation:
let the 3rd side, the hypotenuse, be x
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 2² + 3² = 4 + 9 = 13 ( take square root of both sides )
x =
Answer:
√13 or 3.6
Step-by-step explanation:
It is a right triangle and you have the measure of the cathets, we use the Pythagorean theorem
