Add three to the product of 4 times twelve
Answer:
420
Step-by-step explanation:
Assuming this is the problem:
At a school, 147 students play at least one sport. This is 35% of the students at the school. How many students are at the school?
147/35 = x/100
35x=147*100
35x=14,700
x=420
Answer:
flips, reflection y rotation
Step-by-step explanation:
Answer:
p = -2 ±sqrt( 5)
Step-by-step explanation:
p^2 + 4p = 1
Take the coefficient of p
4
Divide by 2
4/2 =2
Square it
2^2 = 4
Add it to each side
p^2 + 4p+4 = 1+4
(p+2) ^2 = 5
Take the square root of each side
sqrt((p+2) ^2) =±sqrt( 5)
p+2 = ±sqrt( 5)
Subtract 2 from each side
p+2-2 = -2 ±sqrt( 5)
p = -2 ±sqrt( 5)
