Answer:
B) 72
Step-by-step explanation:
28+(17x+4)=4+24x
17x+32=24x+4
32=24x-17x+4
32=7x+4
7x=32-4
7x=28
x=28/7
x=4
WGH=17x+4=17(4)+4=68+4=72
Answer:
STQ
Step-by-step explanation:
Triangle STQ is the correct option
Answer:
1.2×1.3=1.56
Step-by-step explanation:
1.2 ×1.3=1.56
For this case we have the following polynomials:

To divide the polynomials we must follow the following steps:
1) Same base, the exponents are added.
2) Only terms that have the same exponent can be added or subtracted.
3) If the remainder is zero, the division is exact.
Answer:
Note: see attached image for the solution.
To solve the equation, divide by 4 on both sides to isolate the variable:
4x = 30
4x/4 = 30/4
x = 7.5
