Answer:
a = - 6
Step-by-step explanation:
Given
f(x) = 3x + 5 , then
f(a) = 3a + 5 and f(a) = - 13 , then equating the right sides
3a + 5 = - 13 ( subtract 5 from both sides )
3a = - 18 ( divide both sides by 3 )
a = - 6
The perimeter of a rectangle is twice the sum of length and width, so the sum of length and width is half the perimeter, 10 3/4 ft.
The width will be the difference between this and the length, hence 5 1/2 ft.
The area is the product of length and width.
A = length×width
A = (5.25 ft)×(5.5 ft) = 28.875 ft²
The area of the sandbox is 28 7/8 ft².
The question has omitted options but i will solve, so you will just check my answer from the options you have.
Answer: The equation to find the value of x = 3x+ 2= 5x-4
The value of x= 3
Step-by-step explanation:
Step 1
The sum of 3 times the value of x and 2 is equal to four less than five times the value of x can be expressed as
3x+ 2= 5x-4
Step 2
Solving this equation to find the value of x , we have that
3x+ 2= 5x-4
3x-5x= -4-2
-2x= -6
x= -6/-2
x=3
41/11
