Answer:
110 cm²
Step-by-step explanation:
The area of a triangle is 1/2 times base times height.
A = 1/2bh
A = 1/2(22)(10)
A = 110
Given:
m/n-3(m+n)
m=-10 and n=-2
Solving:
-10/-2-3(-10-2) Since m=-10 and n=-2, we substitute them in for the values since they have an equal relationship.
Now, follow Orders of Operations: PEMDAS
-10/-2-3(-12) Simplify parentheses (P)
There are no Exponents (E)
Multiplication (M) and Division (D) are =, so we do whatever operation comes from the left to right.
-10/-2=5 Division comes first on the left.
therefore:
5-3(-12)
-3(12)=-36, Multiplication is last on the right.
therefore:
5-36
5-36=-31 After M/D, we do Addition and Subtraction, which are also =, so we do them left to right.
Therefore -10/-2-3(-10-2)=-31
Answer:
Step-by-step explanation:
B: to get 4/8 = 1/2 That is not the whole answer, but it gets one started.
D: Very large because -4 -(-9) = 5 That's the power. This is going to make the result large.
That's all I would pick, but the second from the bottom might be an answer.
Answer:
it would be 68° because the relationship is a vertical angle
