(5)^x=(2^3)^x-7
x=3x-21
-2x=-21
10.5
Answer:
The correct option would be x^3
Step-by-step explanation:
The amount that you can take away from both of the numbers would be the correct answer.
The answer would basically be the lowest number that is there
Say you have x^7 and x^4
The GCF would be x^4
Step-by-step explanation:
Sum of angles in a triangle = 180°.
Question 3:
We have 90° + 61° + (14x + 1)° = 180°.
=> 14x° + 152° = 180°
=> 14x° = 28°
=> x = 2.
Question 4:
We have 70° + 55° + (4x + 3)° = 180°.
=> 4x° + 128° = 180°
=> 4x° = 52°
=> x = 13.
the answer is 21+2=(32-14)
Answer:
Step-by-step explanation: largest=2x+4
their sum =2x+2x+4=36
4x=36-4=32
x=32/4=8
so the numbers are 2*8,2*8+2,2*8+4
that is 16,18,20
