Maggie made 3 stacks of wooden blocks. the first stack was 12 blocks tall. the second stack was 3 blocks taller than the first. the third stack was 7 blocks shorter than the second stack. how many blocks did maggie use in all?
a: 15
b: 8
c: 27
d: 35

Choose the number sentence that shows the identity property of addition. a. 122 = 61 + 61 b. 62 = 1 + 61 c. 61 = 0 + 61

The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph.which is the residual value when x = –2? a)–2 b)–1 c)1 d)2

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
