The first six rows of Pascal's triangle are shown. David decided to add the numbers in each ron. He found the sum of the first row was 1.t the second row was 2. and the sum of the third row was 4 1 1 1 1 2 1 3 3 1 6 4 1 10 10 5 1 1 1 1 5 Based on the pattern in the triangle, what is the sum of the numbers in the seventh row what is the sum of the seventh row

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
