Let's multiply all the terms in 5 :
5y=-3x+15
Answer:
6x² - xy - 15y²
Step-by-step explanation:
To multiply these two binomials together, we can use FOIL. FOIL stands for:
First: Multiply the first terms of the binomials together.
Outer: Multiply the first term of the first binomial by the second term of the second binomial.
Inner: Multiply the second term of the first binomial by the first term of the second binomial.
Last: Multiply the second (last) terms of the two binomials together.
(3x - 5y)(2x + 3y) = (3x)(2x) + (3x)(3y) + (-5y)(2x) + (-5y)(3y)
= 6x² + 9xy - 10xy - 15y²
= 6x² - xy - 15y²

Answer:
To find the dimensions of the flower bed, we can set up an equation based on the given information. Let’s assume the length of the shortest side is x. According to the problem, one side is twice the length of the shortest side, which means it is 2x, and the third side is 15 feet more than the length of the shortest side, which means it is x + 151.
The perimeter of a triangle is the sum of all its sides. In this case, we have:
x + 2x + (x + 15) = 143.
Simplifying the equation, we get:
4x + 15 = 143.
Subtracting 15 from both sides of the equation, we have:
4x = 128.
Dividing both sides of the equation by 4, we find:
x = 32.
Now that we know the value of x, we can find the lengths of all three sides:
Shortest side: x = 32 feet.
Side twice the length of the shortest side: 2x = 64 feet.
Third side: x + 15 = 47 feet.
Therefore, the dimensions of the flower bed are approximately 32 feet, 64 feet, and 47 feet.
7 gallons of milk will cost $29.33.
A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is that 4 gallons of milk cost $16.76.
Now, we can write that -
4 gallons of milk cost $16.76
1 gallon of milk will cost $(16.76/4)
7 gallons of milk will cost $(16.76/4 x 7) = $29.33
Therefore, 7 gallons of milk will cost $29.33.
