4. In the exit slip, Brady got everything wrong. He needed to factor

x2 - 10x + 25 and 16x2 -9. This is his work.

x2 - 10x + 25 = x2 - 10x + 52

= x2 - 2(x)(5) + 52

= (x + 5)(x - 5)

16c2 – 9 = (40)2 – (3)2

= (40 - 3)2

Identify the error(s) in planning the solution or solving the problem. Write

the correct solution.

(1)The error is in third step.

The correct solution is (x-5)²

(2)The error is in third step.

The correct solution is (4c+3)(4c-c)

Step-by-step explanation:

(a-b) whole square is the sum square of a and b and subtraction of product of 2,a and b.

(a-b) = a²+b²-2ab

Therefore,

x²-10x+25

=x²-2.x.5+5²

=(x-5)²

The error is in third step.

The correct solution is (x-5)²

The subtraction of square of b from square a is the product of sum of a and b and the subtraction a from b.

(a²-b²)=(a+b)(a-b)

16c²-9

=(4c)²-3²

=(4c+3)(4c-c)

The error is in third step.

The correct solution is (4c+3)(4c-c)

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

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.
