PLEASE HELP (image included) Graph the solution of the equation b - 11 = -8

lesantik [10]

It is the third number line.

b-11=-8

What minus 11 would equal -8? 3!

8+3=11 so it would make sense that the dot would be on 3.

smaller numbers minus larger numbers (such as this equation) always end up being negative, so if you have the answer and at least one of the other numbers, it will be easy to figure out.

In this case you would want to maybe just imagine 11-8=? or go 8+?=11.

11-8=3 and 8+3=11. There you would have your missing number.

The diagonals of a rhombus are 21 m and 32 m. What is the area of the rhombus?<br> 30 POINTS

Wittaler [7]

I have included attachment below

so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2

answer is 336 m^2
