Step-by-step explanation:

Step 1: Define

Identify

Point (1, 5)

Point (-8, 4)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-8-1)^2+(4-5)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-9)^2+(-1)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{81+1}$
[√Radical] Add: $\displaystyle d = \sqrt{82}$

What is the sum of 5x*2 +3x-7 and 12x+12

Gemiola [76]

Answer:25x + 5

Step-by-step explanation:

(5x * 2 + 3x - 7) + (12x +12)

= (10x +2x - 7) + (12x + 12)

= (13x - 7) + (12x + 12)

Expand the brackets

= 13x - 7 + 12x + 12

Join like terms together

= 13x + 12x + 12 - 7

= 25x + 5

A student solved this problem and said the answer is 12 pounds. Heather had 6 3/4 pounds of apples. She bought another 5 1/2 pou

Nataliya [291]

The answer is D because 6 3/4 in an improper fraction is 27/4. 5 1/2 in an improper fraction is 11/2. If you want to add 27/4 and 11/2, then you have to multiply both the numerator and denominator of 11/2. Now, 11/2 will be turned into 22/4. 27/4+22/4=49/4. Now, you have to turn 2 1/4 into an improper fraction to subtract. 2 1/4 will be turned into 9/4. 49/4 - 9/4=40/4. 40/4 is simplified to 10. So the answer is, D.

Hope that helped :)
