Answer:
The first term is 3. The common difference is 2.
Step-by-step explanation:
The first term is x.
The common difference is d.
The second term is x + d.
3rd term: x + 2d
4th term: x + 3d
7th term: x + 6d
"The fourth term of an Arithmetic Sequence is equal to 3 times the first term"
x + 3d = 3 * x Eq. 1
"the seventh term exceeds twice the third term by 1"
x + 6d = 2(x + 2d) + 1 Eq. 2
Simplify Eq. 1:
2x = 3d
Simplify Eq. 2:
x + 6d = 2x + 4d + 1
x = 2d - 1
Multiply both sides of the last equation by 2.
2x = 4d - 2
2x = 3d (simplified Eq. 1)
Since 2x = 2x, then the right sides are equal.
3d = 4d - 2
d = 2
2x = 3d
2x = 3(2)
2x = 6
x = 3
Answer: The first term is 3. The common difference is 2.
Answer:
25.047 or roughly 25.
Step-by-step explanation:
I solved it wrong the first time then i double check with wolframalpha and got the correct number.
We know that the area of the tile is 18 
and it makes a triangle, we also know the base and height. In this case the base is 2
and the height is also given which is 
.
Area of triangle = 
,
substituting we will end up with 18 =( 2 * ) / 2
Here is the tricky part 
, i totally forgot about that lol.
Simplifying: we will get 18 = 
Now, in order to find the x, we will need to take the log of both sides.
Solving for x we end up getting:
= x
where x = 25.047.
To be honest I deserve a nobel prize not a brainliest lol.
Good question bro, take it easy.
Answer:
U cannot use factorisation method to solve this, we are to use formula method
Step-by-step explanation:
6x²+7x=1
Answer:
List the factors of 12
1,12
2,6
3,4
That is the side lengths of the 3 rectangles
All the areas will be 12 because they are the factors 12
factors multiply to be a number
(length + width) x 2 = perimeter
1+12=13x2=26
1 by 12 has a perimeter of 26 and area of 12
2 by 6 has a perimeter of 16 and area of 12
3 by 4 has a perimeter of 14 and area of 12
