Gaira was asked to evaluate the algebraic expression –3. 8x 6 when x = –7. 5. –3. 8(–7. 5) 6(–7. 5) 28. 5 (–45) (–16. 5) What mistake did she make? What is the correct answer?.

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
