Which correctly shows this equation
solved for w?
The equation solved for w is:
w = A/l
The correct option is A.
What is an equation?A pair of algebraic equations with the equal symbol (=) in the center and the same value are referred to as an equation.
Starting with the equation:
A/l = lw/l
We can simplify it by multiplying both sides by l:
A = lw
To solve for w, we need to isolate it on one side of the equation.
We can do this by dividing both sides by l:
A/l = w
Therefore, the required equation is A/l = w.

Answer:
a broom handle - line segment
the letter T - perpendicular lines
a sun ray - ray
a cookie crumb - point
the horizon - line
row of seats of airplane - parallel lines
Step-by-step explanation:
a broom handle is straight and has a beginning and end, same goes for a line segment
the letter T has two lines that intersect with one another, these lines are perpendicular
a sun ray is well, a ray
a cookie crumb is small and round, similar to a point
lines do not have a beginning or end, like the horizon line
and the row of seats on an airplane all line up together like lines that are parallel.

Suppose ABCD is a parallelogram. If AB = 9x + 2, CD = 12x - 4, BC = x + 7, determine the length of AD.
Need help asap
======================================================
Explanation:
For any parallelogram, the opposite sides are parallel and are the same length.
AB = CD
9x+2 = 12x-4
2+4 = 12x-9x
6 = 3x
x = 6/3
x = 2
Which leads to
AB = 9x+2 = 9(2)+2 = 20CD = 12x-4 = 12(2)-4 = 20BC = x+7 = 2+7 = 9Side AD is opposite BC, so AD = BC = 9

Answer: B
Step-by-step explanation:
solve this 6(x+4)+1=x+5
[tex] \sf :\implies \quad {\pmb{x = - 4}}[/tex]
Solution:Let's solve the given equation step by step ;
[tex] \sf :\implies \quad 6(x + 4) + 1 = x + 5[/tex]
The first step is to distribute the equation:
[tex] \sf :\implies \quad (6 \times x ) + (6 \times 4) + 1 = x + 5[/tex]
[tex] \sf :\implies \quad 6x + 24 + 1 = x + 5[/tex]
[tex] \sf :\implies \quad 6x + 25 = x + 5[/tex]
Second step is to combine the like terms:
[tex] \sf :\implies \quad 6x + 25 - x = 5[/tex]
[tex] \sf :\implies \quad( 6x - x) + 25 = 5[/tex]
[tex] \sf :\implies \quad 5x + 25 = 5[/tex]
Now, subtract 25 from both sides :
[tex] \sf :\implies \quad 5x + 25 - 25 = 5 - 25[/tex]
[tex] \sf :\implies \quad 5x = - 20[/tex]
Divide both sides by 5:
[tex] \sf :\implies \quad \dfrac{5x}{5} = - \dfrac{20}{5} [/tex]
[tex] \sf :\implies \quad \boxed{ \pmb{\sf x = - 4}}[/tex]
Hence, your answer is ; x = -4

Answer:
Ivy is correct
Step-by-step explanation:
the perimeter of a parallelogram can be written as P= 2(a+b), where a and b are the lengths of the sides of the parallelogram.
since the parallelogram has been dilated by a scale factor of 0.6, we multiple the original side lengths by 0.6.
12 × 0.6 = 7.2
16 × 0.6 = 9.6
Plug into the equation
P=2(7.2+9.6)
P=2(16.8)
P= 33.6
You can also solve by plugging in the original values and multiplying the answer by 0.6.
P=2(12+16)(0.6)
P=2(28)(0.6)
P=(56)(0.6)
P=33.6

what two numbers multiply to get -8 and add to get 4?
Answer:
-2-2√3, -2+2√3
Step-by-step explanation:
Let x and y be two numbers.
Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:
x(-4-x) = -8
-4x -x^2 = -8 . . . . . eliminate parentheses
x^2 +4x = 8 . . . . . . multiply by -1
x^2 +4x +4 = 12 . . . add 4 to complete the square
(x +2)^2 = 12
x +2 = ±√12 = ±2√3

what is 20 - 10
what is 20+ 10
Answer:
20-10=20
20+10=30
Step-by-step explanation:
For 20-10 let's assume John has 20 apples. He gives 10 to Carol.
Understand that subtraction can mean taking away or finding a difference. For example, 13 – 8 can mean, “How many are left when you take 8 away from 13?” Or, 13 – 8 can be interpreted as, “How much more is 13 than 8?” Understand that subtraction is the opposite of addition. Know the addition facts up to 9 + 9.
If john has 20 apples and gives 10 to carol, he will have 10 left.
For 20+10, we do the opposite operation, which is addition.
Addition is finding the total value of two or more numbers. Addition is shown using the + symbol in maths sums.
If john has 20 apples and buys 10 more, he will have 30 apples.
