Tyra solved the quadratic equation x2-10x -24 = 0by factoring. Her work is shown below:
Step 1: x2-10x -24 = 0
Step 2: x2-4x - 6x - 24 = 0
Step 3: (x2-4x) + (-6x - 24) = 0
Step 4: x(x-4) - 6(x - 4)=0
Step 5: (x-4)(x-6)=0
Step 6: x-4 = 0, x-6 = 0
Step 7: x=4 or x = 6
Step 8: 4, 6
Tyra did not find the correct solutions. Investigate the steps, decipher her mistakes, and explain how to correct Tyra’s work.
Answer:
Step 5 was not correct
Step-by-step explanation:
Tyra cannot take x and 6 common and then remove those valuse.

One apple costs$ 0.55 at the grocery store. Customers receive one free apple for every 88 apples that they buy. Anna paid a total of $8.80 for her apples.
How many free apples did Anna receive?
Answer:
0 free apples

8.80 ÷ 0.55 = 16 apples
Anna didn't receive any free apples as she didn't pay for 88 apples and more.
Tyrone is working with two other students to build a border around the school’s triangular garden. Each student brought in one side of the border, but they all used different units to measure the side lengths. The first side is 312 inches long, the second side is 20 feet long, and the third side is 12 yards long. If the measurements need to be in feet, will the three border pieces make a right triangle?
Convert the first side into feet using a proportion.
Answer:
NO, the these three border pieces will not make a right triangle
Step-by-step explanation:
Perform the necessary conversions:
1. 312 in converts to
312 in 1 ft
----------- * ------- = 26 ft
12 in 1
2. 20 ft
3. 12 yd converts to
12 yd 3 ft
------------- * --------- = 36 ft
1 yd 1
So the three different side lengths are 26 ft, 20 ft and 36 ft.
For the three pieces to make a right triangle, these measurements must satisfy the Pythagorean Theorem:
26² + 20² = 36², or 1296
676 + 400 = 1076
The Theorem is NOT satisfied, and so NO, the these three border pieces will not make a right triangle.

Figure A maps to figure B with a scale factor of 1 1/2.
What is the value of x?
Answer:
x = 6/2 = 3
Step-by-step explanation:
This is a dilation. A dilation is a change in size, whether it is an enlargement or reduction.
The scale factor is how much the enlargement is.
The side of Figure A is 2.
So we must multiply 2 ⋅ 1 1/2.
2 ⋅ 1 1/2 (3/2) = 6/2
6/2 is equal to 3.
Therefore, the value of x in Figure B is 3.
