One spring, a group of students measured rainfall totals at their school. This chart shows how many inches of rain the students measured each month.
How many more inches did it rain in May than in April?
MONTH
March 5.7
April6.3
May13.8

Subtract the values for May and April

13.8 - 6.3 = 7.5

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
