In the diagram below, the length of a square is (3x + 7) units. the dimensions of the cut-out rectangle

are x by (2x + 5) units. which choice expresses the area of the shaded region (green region), in square units?

Write an expression that has three terms and simplifies to 4x - 7. identify the coefficient(s) and constant(s) in your expression

Is the point (0, 8) on the x-axis or y-axis? how do you know?

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
