~AH1807Step-by-step explanation:
2x x(x-1) = x x (x+4)
2x x (x-1) - x x (x+4)= 0
2x^2 - 2x - x x (x+4) = 0
2x^2 - 2x - x^2 - 4x = 0
x^2 - 2x - 4x = 0
x^2 - 6x = 0
x x (x-6) = 0
x = 0
x - 6 = 0
x = 6
The equation has 2 solutions
x1 = 0, x2 = 6

Please help calculate the surface area
Answer:
SA = 189 cm^2
Step-by-step explanation:
What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!
Starting with triangles: area = 1/2 * l * h
So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2
Since we have two triangular sides, that totals to 24 cm^2.
Then the rectangular sides: area = l*h
so, 5*11 = 55 cm^2
We have three rectangular sides, totalling 165 cm^2
165+24 = 189 cm^2
Answer:
200 [tex]cm^{2}[/tex]
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base(triangle)
LA = ph p = perimeter of base and h = distance between bases
LA = (5 + 5 + 6)11 = 176
B = bh/2 = 6(4)/2 = 12
SA = 176 + 2(12) = 176 + 24 = 200 [tex]cm^{2}[/tex]

HELPPPPPP PLEASEEE !!! After how many missing assignments will a student likely have a zero for an average? (Remember to draw your line of best fit)
Answer:
After 7 assignments and for the line of best fit you want to draw a line where half of the dots are on ether side of the of the line but it also has to fallow the flow of the dots.
Which number line model represents the expression 6+(-2)?
Number line model represented in option C represents the expression 6 + (-2).
What is Number Line?Number line is a pictorial representation of numbers, both negative and non-negative numbers, written on a horizontal straight line within specific intervals.
Number line are used to determine basic mathematical operations like addition, subtraction, division and multiplication.
So here, we are adding the value -2 with 6.
First draw an upward arrow from 0 to 6 in order to represent that we are initiating the addition process with 6.
Then the number -2 added to 6 implies that the number 2 is actually deducting from 6.
So we draw a downward arrow to unit units from 6.
Then we get the number 4 corresponding to the point where the arrow ends.
Hence, option C is the model which represents the expression 6 + (-2).

(cosA+sinA)
2
+(sinA−cosA)
2
=2
Answer:
Here we want to solve:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
First, remember the two expansions:
(a + b)^2 = a^2 + 2*a*b + b^2
(a - b)^2 = a^2 - 2*a*b - b^2
Using these relations, we can expand:
(cos(A) + sin(A))^2 = cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2
( sin(A) - cos(A))^2 = sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2
Replacing that in our equation, we geT:
(cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2) + (sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2) = 2
We can simplify this to get:
2*cos(A)^2 + 2*sin(A)^2 + 2*cos(A)*sin(A) - 2*cos(A)*sin(A) = 2
2*cos(A)^2 + 2*sin(A)^2 = 2
We can take the 2 as a common factor to get:
2*cos(A)^2 + 2*sin(A)^2 = 2*( cos(A)^2 + sin(A)^2) = 2
Now we can divide both sides by 2:
2*( cos(A)^2 + sin(A)^2)/2 = 2/2
cos(A)^2 + sin(A)^2 = 1
And this is a trigonometric property that is true for any value of A.
So the equality:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
is true for any real value of A.

We have
Area of inner frame :16*20=320cm²
For
Total area =464cm²
(20+2x)(16+2x)=464cm²
320+32x+40x+4x²=464cm²
4x²+72x+320-464=0
4x²+72x-144=0
4(x²+18x-36)=0
x²+2.9.x+9²=9²+36
(x+9)²=117
x+9=√117
x=10.81-9
x=1.82[approximately]
So
width of frame;20cm+1.82+1.82=23.64cm
length: 16+1.82+1.82=19.64cm
