Answer:
Step-by-step explanation:
This question is illustrated using the attachment and will be solved using cosine formula
<em>Let the strawberry side be s, the Green beans be b and the pumpkins be p.</em>

Answer:
2
Step-by-step explanation:
so subsitute the letters so rhe equation would look like
my- 2x
3×6-2×8
18-2×8
18-16
2
The answer would be 28.

Here's my work:
Remember PEMDAS:
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
Also, remember to always go left to right.
(6+2)^2-4*3
Square everything in the parenthesis.
36+4-4*3
Multiply where you see a multiplication symbol from left to right.
36+4-12
Add.
40-12
Subtract.
28
Done!

I hope I was able to guide and help you on this.
Muitply by two on both sides then subtract then divide to find x
Answer:
Range is {y | y ≥ –11}
Step-by-step explanation:
This is quadratic equation.
<em>A quadratic equation's range can be found if we find the vertex.</em>
For quadratic equations that have a positive number in front of , it is upward opening and thus <u>all the numbers greater than or equal to the minimum value of vertex is the range.</u>
The formula for vertex of a parabola is:
Vertex =
Where,
- is the coefficient of
- is the coefficient of
From our equation given, and
Now, coordinate of vertex is
coordinate of the vertex IS THE MINIMUM VALUE that we want. We get this by plugging in the value [ ] into the equation. So we have:
Hence, the range would be all numbers greater than or equal to
Third answer choice is the right one.
