(x−8)2=(x+−8)(x+−8)=(x)(x)+(x)(−8)+(−8)(x)+(−8)(−8)=x2−8x−8x+64=x2−16x+64

(x−8)2=x2−82Step 1: Simplify both sides of the equation.x2−16x+64=x2−64Step 2: Subtract x^2 from both sides.x2−16x+64−x2=x2−64−x2−16x+64=−64Step 3: Subtract 64 from both sides.−16x+64−64=−64−64−16x=−128Step 4: Divide both sides by -16.−16x−16=−128−16x=8

The teacher separated her class of twenty-eight students into two groups. One group has 4 more than twice as many students as th

wariber [46]

4+2x = x (x = student in smaller group)

4 + 2x + x = 28 (total # of students)
4+ 3x = 28
3x = 24
x = 8
8 students in the smaller group
4 + 2(8) = 20 students in the larger group

viktelen [127]

Add 3/4 foot to 2/12 foot. The LCD here is 12.

Thus, add 9/12 foot to 2/12 foot. Answer: 11/12 foot.

Are you sure you copied down that "2/12" correctly? Note that 2/12 = 1/6

My metric bolt measures .780 with calipers over the threads what size is it

attashe74 [19]

Bolts are usually classified in terms of two types of measurements: the metric system and the imperial system. In calipers, the metric system is in units of millimeters, while the imperial system is in units of inches. For example, when a bolt is sized as 12 × 1.25 in the metric system, that means the bolt thread diameter measures 12 mm, and the thread pitch measures 1.25 mm.

So, if your metric bolt measures 0.78 over the threads, that means that the size of the bolt is 0.78 mm in thread pitch. The attached picture shows how you measure the thread pitch.
