Answer:
12. -11
13. 2
Step-by-step explanation:
12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction
For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.
From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.
Your new equation is -10-8+7 = -11
13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))
- keep in mind there’s an addition between the two
Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17
Second multiply 5 x -3 = -15
Now you can combine the two answers using addition: 17 + (-15) = 2
Answer:
4/6
Step-by-step explanation:
this is going to be your answer because 2/6 is 1/3 cup and then 4/6 is 2/3 of a cup.
Doing factorization, we know that the factors of the given equation are ±√5 and ±10i.

What is Factorization?</h3>
In mathematics, factorization or factoring consists of writing a number or any mathematical item as a product of several factors, typically small or easier objects of the same.
For example, 3 × 5 is a factorization of an integer 15 and is a factorization of an equation x² – 4.
So, we have the equation:
x⁴ + 95x² – 500 = 0
Factorizing the above equation:
x⁴ + 100x² - 5x² - 500 = 0
x²(x² + 100) - 5(x² + 100) = 0
(x² - 5)(x² + 100) = 0
Solving further:
x² = 5
x² = -100
x = ±√5
x = √-100
Factors: ±√5 and ±10i
Therefore, doing factorization, we know that the factors of the given equation are ±√5 and ±10i.

Answer:
2, 7, 27, 42
Step-by-step explanation:
y = 5*1 -3 =2
y = 5*2 -3 =7
y = 5*6 -3 = 27
y = 5*9 -3 = 42
