![V\times V→V ,( x_{1} ,x_{2} ,x_{3})+( y_{1} ,y_{2} ,y_{3})=( x_{1} +y_{1},x_{2}+y_{2},x_{3}+y_{3})](https://tex.z-dn.net/?f=V%5Ctimes%20V%E2%86%92V%20%2C%28%20x_%7B1%7D%20%2Cx_%7B2%7D%20%2Cx_%7B3%7D%29%2B%28%20y_%7B1%7D%20%2Cy_%7B2%7D%20%2Cy_%7B3%7D%29%3D%28%20x_%7B1%7D%20%2By_%7B1%7D%2Cx_%7B2%7D%2By_%7B2%7D%2Cx_%7B3%7D%2By_%7B3%7D%29%20)
Around 76% were correct.
How:
17-4 is 14, when you would do 14/17 to get .76.
.76•100 is 76%
Answer:
12 inches
Step-by-step explanation:
15 - 3 = 12
The board is 12 inches long.
_____
A measuring tape is like a number line. To find the distance between two numbers on the number line, you subtract the smaller one from the larger one. The tape measure works the same way. Subtract the number at one end of the board from the number at the other end of the board to find the length of the board.
Answer:
Step-by-step explanation:
1.)
10p² - 7 = 243
10p² = 250
p² = 25
p = ±5 (meaning p can both equal -5,5)
2.)
9b²+9 = 684
9b² = 675
b² = 75
b = ±√75
= ± 5√3
