If the point (a, b) was translated 7 units to the left and 5 units down and then reflected across the x-axis, its new coordinates, in terms of a and b would be (1) (-a + 7, b + 5)
(2) (a + 7, b + 5)
(3) (a - 7, -b + 5)
(4) (-a - 7, -b - 5)

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
