What is the formula for area of a rectangle? I'm not sure if my answer is correct if it is incorrect which is the correct answer?

Given: △abc, ab=15, bd=9 ad ⊥ bc , m∠c=30°. find: the perimeter of the triangle.

Match each equation with the operation you can use to solve for the variable. 1 subtract 10 2 divide by 10 3add 18 4add 10 5 subtact 18 6multiply by 5. 7multiply by 10. a 5 = 10p b p + 10 = 18 c p + 18 = 5 d 5p = 10

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers
