∆ on the Left;

x + 95 + 35 = 180°

x + 130 = 180°
x = 50°

In the middle:

50° + 63° + x= 180°

113° + x = 180°

x = 67°

∆ on the right:

67° + 85° + x = 180°

152 + x = 180°
x = 28°

Step-by-step explanation:

if that's x^2+25

they can be factored to x+5

because the factor of x^2 is x cause x multiplied by x is x^2 and the factor of 25 is 5 cause 5×5 is 25

The expression (x^-8) (x^3) is equivalent to the expression x^n. what is the value of n?

mash [69]

Answer:

n=-5

Step-by-step explanation:

You must multiply $x^{-8}*x^{3}$ . The laws of exponents state that when multiplying exponents of the same base, you can just add the exponents and raise the base to the sum of the exponents. So, $x^{-8}*x^{3}=x^{(-8+3)}=x^{-5}$ . Since our end product is $x^{-5}$ , n is equal to -5.
