Answer:
2x -16
Step-by-step explanation:
The area of each rectangle is the product of its length and width. The shaded area is the difference between the areas of the outside rectangle and the inside rectangle.
shaded area = (2x -1)(x +6) -(2x +5)(x +2)
= (2x^2 +11x -6) -(2x^2 +9x +10)
= (2 -2)x^2 +(11 -9)x +(-6 -10)
= 2x -16 . . . . . area of the shaded region

The area of a rectangular vegetable patch is 32 square meters. The perimeter is 24 meters.
What are the dimensions of the vegetable patch?
Please help
Answer:
When l = 4m , breadth is 8m
When l = 8m , breadth is 4m .
Step-by-step explanation:
Here it is given that the area of a rectangular patch is 32m² . If we assume length to be l and breadth to be b , then ;
[tex]\longrightarrow Area_{rectangle}=length\times breadth\\ [/tex]
[tex]\longrightarrow 32m^2 = lb \dots (i) [/tex]
Again , it's given that the perimeter is 24m .We know that perimeter of a rectangle is ,
[tex]\longrightarrow Perimeter = 2(l+b)\\ [/tex]
[tex]\longrightarrow 24 = 2( l +b)\\ [/tex]
[tex]\longrightarrow l + b = 12\dots (ii) [/tex]
From equation (i) and (ii) , we have ;
[tex]\longrightarrow l + \dfrac{32}{l}=12\\\\\longrightarrow \dfrac{l^2+32}{12}=1\\\\\longrightarrow l^2+32=12l \\\\\longrightarrow l^2-12l +32=0\\\\\longrightarrow l^2-4l -8l +32=0 \\\\\longrightarrow l( l -4) -8(l-4)=0\\\\\longrightarrow(l-4)(l-8)=0 \\\\\longrightarrow \underline{\underline{ l = 4,8}} [/tex]
Therefore , we can find breadth as,
[tex]\longrightarrow l + b =12\\\\\longrightarrow b = 12 - l \\\\\longrightarrow b = 12-8, 12-4\\\\\longrightarrow \underline{\underline{b = 4,8}}[/tex]

Answer: f(x) = 3x^(2)-2x+1
f(x) = 3x^(2)-2x+1 = y-intercept (0, 1).
g(x) = -10x^(2)+50x = y-intercept (0, 0).
As we see, the first equation (f(x) = 3x^(2)-2x+1) has a y-intercept of (0, 1), while the other equation (g(x) = -10x^(2)+50x) has a y-intercept of (0, 0). This means that the quadratic equation that has the greatest y-intercept is f(x) = 3x^(2)-2x+1, which is (0, 1).

help me find total surface area
Answer:
144 square feet
Step-by-step explanation:
First. the base is 6 by 6, meaning the surface area of it is 36 square feet. Then, we do a single triangle, whose area is (6*9)/2, or 27. 27*4 is 108, so the answer will be 108+36=144.
Answer is: 144 square feet

The product of a number and ten is twelve
translate into algebraic equation and solve
Answer:
The number is 1.2 and the algebraic equation is 10x=12
Step-by-step explanation:
Since the product of a number and ten is 12, we can express it as the algebraic equation x*10=12, where x is any number.
x*10=12
10x=12
x=12/10
x=1.2
Therefore, The number is 1.2

Which expression calculates the speed in meters per second of an object that travels a distance of 40 m every 10 s?
10÷40
or
40 + 10
or
40/10
or
40×10
Answer:
40/10 [4 meters/sec]
Step-by-step explanation:
Watch for what the units are telling us. The number that is being requested
is speed in units of meters/sec. We are given 40 meters and 10 seconds. If we divide 40 meters by 10 seconds (10 meters/10 seconds), we get 4 meters/sec, the correct dimension.

What is the equation of the line????????
Answer:
y=1/2x+2
Step-by-step explanation:
The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.
To find the gradient is a little more tricky, but we can follow the formula:
[tex]\frac{rise}{run}[/tex], where rise is the vertical value and run is the horizontal value
So we sub in our values:
[tex]\frac{2}{4}[/tex]
And simplify:
[tex]\frac{1}{2}[/tex]
So now we sub in our new found values into y=mx+c:
y=1/2x+2
Answer: y = x/2 + 2 which is the 4th option from the top
Step-by-step explanation:
First find the slope which is (0-2)/(-4-0) = 2/4 = 1/2
So it's y = x/2 + c
Substituing (-4,0) into the equation we get
0 = -4/2 + c
0 = c-2
c = 2
So the equation is y = x/2 + 2 which is the 4th option from the top

Answer: z = [tex]\sqrt{10}[/tex]
Step-by-step explanation:
To find z, you must set up a proportion to solve.
To find the altitude of a special right triangle, the formula is:
[tex]\frac{a}{x} =\frac{x}{b}[/tex]
You can use 5 as a and 2 as b to complete the proportion:
[tex]\frac{5}{x} =\frac{x}{2}[/tex]
Next, to solve:
Step 1: Cross-multiply.
[tex]\frac{5}{z} =\frac{z}{2}[/tex]
(5)*(2) = z*z
10 = z²
Step 2: Take square root.
10 = z²
√10 = z
