When you combine terms with exponents, why do you not combine the exponents? For example, (3x^2 + 2) + (3x^2 + 3)
Why is the answer 6x^2 +5 instead of 3x^4 + 5?

do the parentihesis first

Step-by-step explanation:

77

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
