In ΔSTU, \overline{SU} SU is extended through point U to point V, \text{m}\angle STU = (2x+8)^{\circ}m∠STU=(2x+8) ∘ , \text{m}\angle TUV = (7x-5)^{\circ}m∠TUV=(7x−5) ∘ , and \text{m}\angle UST = (x+19)^{\circ}m∠UST=(x+19) ∘ . What is the value of x?X?

If a(0,0,0) and b(2,2,2) are points in coordinate space, how many paths are there from a to b that move from one lattice point to another in the positive x-,y- or z- direction?

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

What is the number 321,000,000 in scientific notation? also what is the number? ?
