The largest area that can be enclosed will be that of a square (140 ft)/4 = 35 ft on a side. Such a square has an area of (35 ft)² = 1225 ft², not enough for the garden to be 1300 ft². This tells us the solution to the equation you're being asked to write is non-real.
_____
Putting the given numbers in the area equation, you have
... 1300 = 70w -w²
Multiplying by -1 and completing the square, we have
... w² -70w +35² = -1300 +35²
... (w -35)² = 1225 -1300 = -75
Taking the square root shows us the solution is non-real.
... w - 35 = ±√(-75) = ±5i√3
... w = 35 ± 5i√3 . . . . . . . . . after adding 35. These are complex solutions.
Answer:
152 m^2
Step-by-step explanation:
Find the area of the triangle and subtract it from the area of the square
area of half-triangle = 1/2 x base x height = 1/2 x 8 x 13 = 52
since that's for half of the triangle we times it by 2 to get the whole triangle so 104.
area of the square = 16 x 16 = 256
area of shades region = 256 - 104 = 152 m^2
Answer:
B
Step-by-step explanation:
If the form is only allow in
, then B is the only correct form.
Otherwise, A would be correct as well.
Answer:
yupe
Step-by-step explanation:
The considerations of expressions for each expressions are shown below.
<h3>
What is an expression?</h3>
- An expression in mathematics is a combination of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.)
- Expressions and phrases are similar in structure.
- In English, a phrase may involve action on its own, but it does not constitute a whole sentence.
To consider the expressions:
Part 1:
- (x²+15x+65)+(2x-5)*(3x+8)
- (x²+15x+65)+(6x²+16x-15x-40)
- (7x²+16x+25)
The answer to Part 1 is the letter B,
(7x²+16x+25)
Part 2:
- (4x+1)*(3x-4)-(5x²-10x-12)
- (4x+1)*(3x-4)-(5x²-10x-12)
- (12x²-16x+3x-4)-(5x²-10x-12)
- (7x²-3x+8)
The answer to Part 2 is the letter D,
(7x²-3x+8)
Part 3:
- (8x²+19x+4)+(3x+2)*(x-5)
- (8x²+19x+4)+(3x²-15x+2x-10)
- (11x²+6x-6)
The answer to part 3 is the letter A,
(11x²+6x-6)
Part 4:
- (6x+1)*(3x-7)-(7x²-34x-20)
- (18x²-42x+3x-7)-(7x²-34x-20)
- (11x²-5x+13)
The answer to part 4 is the letter C,
(11x²-5x+13)
Therefore, the considerations of expressions for each expression are shown.
