We can say that the area of the figure equals...
5.5 by 9 rectangle - 2 by 2 triangle - 2 by 5 triangle - 9 by 3.5 triangle
5.5 by 9 rectangle = 5.5 x 9 = 49.5 un²
2 by 2 triangle = 1/2 x 2 x 2 = 2 un²
2 by 5 triangle = 1/2 x 2 x 5 = 5 un²
9 by 3.5 triangle = 1/2 x 9 x 3.5 = 15.75 un²
area of figure = 49.5 un² - 2 un² - 5 un² - 15.75 un² = 26.75 un²
answer: 26.75 un²
The sample is his friends. They might be the same group of interests. The sample needs to be random. Even if he went around and grabbed random people he may not have known at his school, it still wouldn't be random bc they could all be bias towards a local sports team or have different interests than someone from somewhere else
Answer:
Points L, M, and N are collinear with M between L and N. LM = 2x + 8 and MN is one half the length of LM. If LN = 42, write and solve an equation to find x.

Answer:
I believe it would be $34.50.
Step-by-step explanation:
If we need to buy 7.5 lbs of walnuts, and each 3/4 lb is $3.45, we need to divide 7.5 by 3/4
7.5/ .75= 10
10 is how many groups of 3/4 lbs fit into 7.5.
Next, we multiply 10 by 3.45.
10*3.45= 34.5
It costs $34.50 to buy 7.5 lbs of walnuts.
Hope this helps :)
