Answer:
A. 9x^4 and 3x^5y
Step-by-step explanation:
there are two ways to solve this:
first way:
You can solve this my substituting numbers for x and y in this case i used 2 for x and 3 for y and see which one is equal to the original equations
the second way is the regular way
when you add or subtract numbers with variables and exponents you want to add the constants and add the exponents in this case 
is the same as 
= 
and you can do the same process for subtraction
= 
Answer:
Choice C
Step-by-step explanation:
the domain is the input values, or the x values
The altitude will be the geometric mean of the lengths, so
. The smaller leg is the hypotenuse of a right triangle sides 4 and
so the usual trig cliche, hypotenuse 8.
Answer: 8
Answer:
B = 38°
Step-by-step explanation:
A straight angle is 180°. If your four angles total a straight angle, then ...
60 +2x +3x +25 = 180
95 = 5x . . . . . . subtract 85
x = 19 . . . . . . divide by 5
2x = 38 . . . . . angle B is 38°
