An accountant reviews a business’s utility bills over the past year.

A clustered bar graph showing the business's gas and electric bills.

Which utility varied the most throughout the year, and approximately what were the highest and lowest levels?

Electric; $220 and $75
Electric; $210 and $20
Gas; $220 and $75
Gas; $210 and $20

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
