The table shows data on the unit 8 test for four different classes and for one student in each class. find each student's grade. round your answer to the nearest tenth. mean standard deviation z score
Jacob 80 6 -0.5
Sophie 87 2.5 1.2
Avery 82 5 2.6
Garrett 84 8 -2.5

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

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)
