PLEASE HELP ASAP GIVING BRAINLIEST
The foreign language teachers at school collected data about the numbers of students in their classes. Two languages, French and Spanish, are taught in both 8th grade and 9th grade. The teachers created the table shown. Approximately what percent of all students in a foreign language class are 9th graders taking Spanish?
A) 56%
B) 52%
C) 27%
D) 21%

27%

Step-by-step explanation:

Add the number of students: 87+86+71+92= 336

Divide the number of 9th grade Spanish students by the total number of students: 92÷336= 0.27

Times by 100 to get a percentage: 27%

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
