To make the expression 4x−2+□(2x+4) equivalent to 2(6x+7), what must be the value in the box? PLSSSSS HELLPPP
Answer:
4 goes in the box
Step-by-step explanation:
The solution of the equation 4x − 2 + y(2x + 4) = 2(6x + 7) will be 4.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Let the value inside the box be 'y'. Then the equation is given as,
4x − 2 + y(2x + 4) = 2(6x + 7)
Simplify the equation, then we have
4x − 2 + y(2x + 4) = 2(6x + 7)
4x − 2 + y(2x + 4) = 12x + 14
y(2x + 4) = 8x + 16
y = 4(2x + 4) / (2x + 4)
y = 4
The solution of the equation 4x − 2 + y(2x + 4) = 2(6x + 7) will be 4.
More about the solution of the equation link is given below.

The back of Dante's property is a creek. Dante would like to enclose a rectangular area, using the creek as one side and fencing for the other three sides, to create a pasture. If there is 960 feet of fencing available, what is the maximum possible area of the pasture?
Answer:
Step-by-step explanation:
960/3. that's 320 a side. They said maximum, I'm guessing they just wanted you to use base times height as if it was a square, since I'm not seeing any other information. the maximum possible area would be, if the sides were 320 each would be 102,400 square feet. Maximum

(x + 8)(x-8)
answer choices
A x2 + 8x + 64
B x²-64
C x² + 64
x2 + 16X - 64
Step-by-step explanation:
we know the formula(x^2-y^2)=(x+y)(x-y)
so (x+8)(x-8)=x^2-8^2=x^2-64
so the right answer is B
Write the equation of the line containing point (-3, 2) and having a slope of 6.
Answer:
y + 2 = 6(x - 3)
Step-by-step explanation:
Point-Slope Form: y + y₁ = m(x + x₁)
Simply plug in your known variables into the point-slope form to find your equation:
y₁ = 2
x₁ = -3
m = 6
y + 2 = 6(x - 3)
17. The area of the large square below is 49 centimetres squared. What are the side lengths of the shaded triangle?
Answer:
12.25,12.25,7
Step-by-step explanation:
Formula of Area of square= length x breadth
In a square all side are equal as we all know that which means if the Area of the square is [tex]49cm^{2}[/tex] if we take the root of 49 it gives us 7 so the length and breadth of the square is equal to 7 as shown in my figure i uploaded. Please excuse my professional drawing skills ( pun intended :D)
The dotted lines i assume shows that sides are being bisected into two equal halves which means the whole side equals 7cm and the half is 7/2 equals 3.5cm so the bottom half side of the triangle is 7cm but the two slant heights we have to find we can find it by using phythogra's theorem
(Hypotnuse)^2=(Length^2) x (Breadth)^2
we need to find just one side of the hypotnuse/slant height then we multiply it by 2 which would gives us both of our hypotnuse sides so
(Hypotnuse)^2= (3.5)^2 x (3.5)^2
(Hypotnuse)^2=150.0625
Apply square root on both sides gives us
[tex]Hypotnuse = 12.25[/tex]
Since the traingle is covered by two slant height's the sides of the traignle are 12.25cm 12.25cm and 7cm

There is a parade coming through town, the route is 2 miles long with 10 foot wide sidewalks along each side. If the crowd is approximately 5 people per 16 square feet, how many people are estimated to be watching?
66 000 people
Step-by-step explanation:Hi there !
1 mile = 5280 feet
2 miles = 2×5280ft = 10 560 feet
Area = 2(10560ft×10ft) = 2×105600ft² = 211200 ft²
How many people are estimated to be watching?16 ft² ................ 5 people
211200 ft².........x people
x = 211200×5/16
= 1056000/16
= 66 000 people
