6x - 19 = 3x + 32
-3x -3x
3x - 19 = 32
+19 +19
3x = 51
--- -----
3 3
x = 17
Angle 1 is 97 degrees.
How i got it: 6(17) - 19 = 3(17) +32
102 - 19 = 51 + 32
83 = 83
83 + 83 = 166
360 - 166 = 194
194/2 = 97
__________________________________________________________
20x + 11 = 25x - 14
-20x -20x
11 = 5x - 14
+14 +14
25 = 5x
---- -----
5 5
5 = x
Angle 1 is 69 degrees.
How i got it: 20(5) + 11 = 25(5) - 14
100 + 11 = 125 - 14
111 = 111
111 + 111 = 222
360 - 222 = 138
138/2 = 69
Hi!
Tip #1: To multiply polynomials, consider the variables separate from the numbers.
So we are multiplying 2xyz * -4x²yz
Let's start by multiplying the variables.
xyz * x²yz
Tip #2: The exponents tell you how many of each variable there are. When multiplying variables, add the exponents. When a variable does not seem to have an exponent, that means there is an invisible exponent of 1! (x =
)
xyz * x²yz = (x + x²)(y + y)(z + z) = x³y²z²
Now multiply the numbers! (just like normal)
2 * -4 = -8
Now combine the numbers with the variables once again.
-8x³y²z²
The answer for 2xyz * -4x²yz is -8x³y²z²
Hope this helps! :)
Answer is 3 hope this helps
I hope it can help you hehe. dint forget give me brainlist hehe
