When simplified, the value of the expression (15 - 11)^2 + square root 64 ÷ 4 is equal to . 24
10
18
4

28

Step-by-step explanation:

Simplify:  (15 - 11)^2 + square root 64 ÷ 4

"Order of operations rules"  apply here.  Any work inside parentheses must be done first:

(15 - 11)^2 = (4)^2 = 16 (since exponentiation is the next operation in priority)

Then we have:

16 + square root 64 ÷ 4 and remember that we must do division and multiplication before addition or subtraction:

16 + sqrt(16)  +  4

Note that sqrt(16) is a POWER function which must be carried out before other operations, yielding:

16 + sqrt(64) + 4, or

16 + 8 + 4, or

(evaluating this from left to right):  24 + 4 =28

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
