Answer:
y = 9
Step-by-step explanation:
1. We know that the line the angles fall on is a straight angle, meaning it's worth 180°.
2. Given the information above, 8y + 96 + 12 = 180.
3. (Solving equation above).
Step 1: Simplify both sides of the equation.
Step 2: Subtract 108 from both sides.
Step 3: Divide both sides by 8.
Step 4: Check if solution is correct.
Therefore, y = 9.
Answer:
The answer is
Step-by-step explanation:
Given: f(x) = 3 + 2x - x²
To compute f(3 + h) substitute x = 3 + h.
Similarly, to compute f(h) simply substitute x = h.
We are asked to compute
f(3 + h) = 3 + 2(3 + h) - {(3 + h)²}
= 3 + 6 + 2h - {9 + 6h + h²}
= 9 + 2h - 9 - 6h - h²
= - 4h - h²
Now, f(h) = 3 + 2h - h²
f(3 + h) - f(h) = -4h - h² - 3 - 2h + h²
= -6h - 3
which is the required answer.
Answer:
Step-by-step explanation:
The first step to solve the exercise is to make the conversion from meters to centimeters.
Since , then the dimensions of the wood board in centimeters are:
Now, you must find the Greatest Common Factor (GCF). The steps are:
- Descompose 100 and 60 into their prime factors:
- Multiply the commons with the lowest exponents:
Therefore, the side lenght of each square must be:
