I’m pretty sure it’s 240 because you multiply then add
The rules of exponents allow you to simplify expressions involving exponents. When multiplying two quantities with the same base, add exponents: xm⋅xn=xm+n x m ⋅ x n = x m + n . When dividing two quantities with the same base, subtract exponents: xmxn=xm−n x m x n = x m − n .
The answer is 10x-14 because you have to multiply in the parentheses
Answer:
45
Step-by-step explanation:
If two lines are parallel and cut by a transversal, corresponding angles are congruent. Angle GEB and angle EFD are corresponding so they are congruent so you can set them equal to each other and solve.
2x - 30 = x + 15 (add 30 to both sides, subtract x from both sides)
X = 45
288/64=4.5
So 4 hours and 30 minutes. I hope this helps, if you have any more questions
