I would have to say SAS because they give 2 sides and an angle. Also 3:4 because the one side is 3 and add 1 for 4, same for 30 and 40.
Answer:
Second option: (-2,-3) and (1,0)
Step-by-step explanation:
Given the system of equations
, you can rewrite them in this form:

Simplify:
Factor the quadratic equation. Choose two number whose sum be 1 and whose product be -2. These are: 2 and -1, then:

Substitute each value of "x" into any of the original equation to find the values of "y":

Then, the solutions are:
(-2,-3) and (1,0)
Answer:
You can go for 1x9, 2x8, 3x7, 4x6, 5x5.
5x5 is the best as it builds a square, which maximizes space.
20*2.50 = $50.
Answer:
11
Step-by-step explanation:
1) lets get rid of the parentheses, we dont really need them:
−22 −4 + 8+ 52 + 2 − 25
Following order of operations we need to work from left to right
so
-22-4=-26
-26+8=-18
-18+52=34
34+2=36
36-25=11
the answer is 11
hope this helps
