Answer:
Should be 13. Sorry if I’m incorrect!
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
2x+7=30
2x=23
X= 23/2 or 11.5
X does not equal 3, therefore the statement is false
Answer:
#1)
Angle A = 30 degrees; 180 - 150 = 30
Angle B = 120 degrees; 180 - 60 = 120
#2)
Angle A = 65 degrees; 180 - 115 = 65
Angle B = 25 degrees; 180 - 155 = 25
The given expression written in the simplest rational exponent form is 
<h3>Writing an Expression in Exponent form</h3>
From the question, we are to write the given expression in exponent form
The given expression is
![\sqrt{x} \times \sqrt[4]{x}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%20%5Ctimes%20%5Csqrt%5B4%5D%7Bx%7D)
In exponent form,

and
![\sqrt[4]{x} = x^{\frac{1}{4} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%7D%20%3D%20x%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D)
Thus,
becomes

Applying the multiplication law of indices, we get

= 
Hence, the given expression written in the simplest rational exponent form is

Answer:
7x-3 = 5x+ 15
2x-3 = 15 (you will need to subtract the variables to get 2x)
2x = 18 (next, add the constants to result up to 18)
x = 9 (lastly, divide the constant 18 with the coefficient 2 to get 9)
