Answer:
sin2αcos2β + cos2αsin2β
Step-by-step explanation:
Given that
sin(A+B) = sinA cos B + cos A sinB
According to the question;
sin(2α+2β) = sin2αcos2β + cos2αsin2β
where A = 2α and B = 2β
What is (8 - 2) - 6?
Answer:
The answer is Zero
Step-by-step explanation:
So you always do what is in the parentheses first no matter what so in this case you would do 8 - 2 which is 6 then you would do the rest of the equation in order so that means if there were multiplication and division and multiplication came second do division first don't just do the multiplication so any way you got the answer 6 and the next step is to subtract 6 from the answer you just got so now your equation is 6 - 6 which is zero hope this helps plz mark me as brainliest

Ashley drew the triangle LMN on the grid below
What is the area of triangle LMN?
Answer:
B. 27 square units
Step-by-step explanation:
Area of ∆LMN = ½(base*height)
base = MN = 6 units
height = distance from L to MN = 9 units
Plug in the values into the formula
Area of ∆LMN = ½(6*9)
Area = ½(54)
Area = 27 square units

Answer:
[tex]\huge\boxed{\sf x = 68\ degrees}[/tex]
Step-by-step explanation:
Let the two congruent angles both be x.
We know that the sum of interior angles of a triangle is equal to 180 degrees.
x + x + 44 = 180
2x + 44 = 180
2x = 180 - 44
2x = 136
Divide both sides by 2
x = 136 / 2
x = 68 degrees
So, Both the angles are of 68 degrees.

~AH1807Rhombus ABCD has a diagonal BD¯¯¯¯¯.
m∠ADB=(4x−12)°
m∠CDB=(3x+6)°
What is the m∠ADC ?
Enter your answer in the box
º
Answer:
Solution given:
m∠ADB=(4x−12)°
m∠CDB=(3x+6)°
m∠ADC =?
Since diagonal BD bisect the angle <ADC
so
m∠ADB= m∠ADC
(4x-12)°=(3x+6)°
4x-3x=6-12
x=12+6
x=18°
again.
<ADB=m∠ADB+ m∠ADC=4×18-12+3×18+6=120°
So
the m∠ADC =120°
As it's a rhoumbus angles are equal

A bag contains yellow balls, pink balls and green balls only.
The ratio yellow balls : pink balls : green balls = 7:3:5.
There are 42 yellow balls in the bag.
Work out the total number of balls in the bag.
What’s the answer
Answer:
90
Step-by-step explanation:
M1 for ( ) 42/7 [x(7+3+5)] soi by 6
=90
Assuming there are only 42 yellow balls in the bag. The total number of balls in the bag is 90 balls.
Total number of ballsFormulate
42×(3+5+7)÷7
Reduce the fraction
42÷7×(3+5+7)
6×(3+5+7)
Hence:
Total number of balls=6×15
Total number of balls=90 balls
Inconclusion the total number of balls in the bag is 90 balls.

Jeremy rounded the weight of his fruit to the nearest whole. He said his bag of apples weighed 4 pounds. What could have been the actual weight of his bag of apples? Group of answer choices
Answer: 3.5 - 4.4 pounds
Step-by-step explanation:
You included no options so I answered with the range of the answer.
When rounding a number up to the nearest whole number, the number needs to have the first decimal being 0.5 and above all the way to 0.9.
When rounding a number down to the nearest whole number, the number needs to have its first decimal being 0.1 to 0.4 to be rounded down.
For instance, 3.5 to 3.9 would get rounded up to 4 pounds.
4.1 to 4.4 would be rounded down to 4 pounds.

Place the indicated product in the proper location on the grid.
(2a^x+1/2b^x)^2
The expression [tex](2a^x + 1/2b^x)^2[/tex] will generally be located towards the upper right quadrant of the grid, with the term [tex]2a^x[/tex] positioned further to the right and the term [tex]1/2b^x[/tex] positioned further towards the top.
To determine the proper location of the expression [tex](2a^x+1/2b^x)^2[/tex] on the grid, let's analyze the components of the expression and their respective positions.
The given expression is [tex](2a^x + 1/2b^x)^2[/tex]. Breaking it down, we have two terms inside the parentheses: [tex]2a^x[/tex] and [tex]1/2b^x[/tex]. These terms consist of variables (a and b) raised to a power (x), along with coefficients (2 and 1/2) multiplying them.
On the grid, we can assign a specific axis for each variable: the horizontal axis for 'a' and the vertical axis for 'b'. The power 'x' indicates that the values will vary along these axes. Since we don't have specific values for 'a', 'b', or 'x', we cannot pinpoint exact locations on the grid.
However, we can make some general observations. The terms [tex]2a^x[/tex] and [tex]1/2b^x[/tex] will have different positions on the grid due to their coefficients. The term with the coefficient 2 will be relatively larger along the horizontal axis compared to the term with the coefficient 1/2, which will be relatively smaller along the vertical axis.
Hence, on the grid, we can expect the term [tex]2a^x[/tex] to be positioned towards the right side, while the term [tex]1/2b^x[/tex] will be positioned towards the top. The exponent '2' outside the parentheses indicates that the entire expression will be squared, so it will be further enlarged.

B is the midpoint of AC. if AB = x+5 and BC = 2x-11, find the measure of AB
Answer:
2 is the answer
Step-by-step explanation:
Answer:
AB = 21
Step-by-step explanation:
Since B is the midpoint of AC , then
BC = AB
2x - 11 = x + 5 ( subtract x from both sides )
x - 11 = 5 ( add 11 to both sides )
x = 16
Then
AB = x + 5 = 16 + 5 = 21

The question is incomplete, as the resources to calculate the distance covered by both are not given.
To solve a question like this;
First, calculate the distance by both, then subtract the smaller distance
Take for instance, after calculating the distance, you have:
[tex]Jimmy= 850m[/tex]
[tex]Jemima = 500m[/tex]
The difference d is:
[tex]d = 850m - 500m[/tex]
[tex]d = 350m[/tex]
i.e. Jimmy traveled 350m much more

What is an equation of the line that passes through the points (0, -3)(0,−3) and (-5, 3)(−5,3)?
Answer:
y = 6/5 x -3
Step-by-step explanation:
Standard equation of a line is expressed as;
y = mx+b
Slope m = y2-y1/x2-x1
Given the coordinates (0, -3)and (-5, 3)
Slope m = 3-(-3)/-5-0
Slope m = 6/5
Since the line cuts the y axis at y = -3, hence b = -3
GEt the required equation;
Recall that y = mx+b
y = 6/5 x + (-3)
y = 6/5 x -3
This gives the required equation
Answer: −6/5x-3
