10089.67cm is your answer but dont trust m answer wait for other ones
Solution:
- Perimeter of Rectangle = 346
Let Required length of breadth be x
- Then, Length of Rectangle = 45 + x
Now, We have ;
- Perimeter of Rectangle = 2(l+b)
- Perimeter of Rectangle = 2 ( 45 + x + x
- 346 = 2 ( 45 + 2x )
- 346 = 90 + 4x
- 346 - 90 = 4x
- 256 = 4x
- x = 256 ÷ 4
- x = 64 inches
So, Length of Rectangle = x + 46
Length of Rectangle = 64 + 46
Length of Rectangle = 110 inches
Now, Breadth of Rectangle = 64 inches.
Answer:
-1960
Step-by-step explanation:
The expression on the left expands to ...
(4x -7)² = (4x)² +2(4x)(-7) +(-7)² = 16x² -56x +49
Matching coefficients, you have ...
Then the expression c(b+a) evaluates to ...
49(-56+16) = 49(-40) = -1960
The speed is 99 kilometers. U welcome
6×10^-3
Step-by-step explanation:
0.006
Move the point to the front of the first number that is from 1 to 9.
In the question it's 6, so you move it to the front of 6 .
And because it's from back to front it has to have a negative sign in its power
which is going to be
6× 10^-3
where 6=the number from 1 to 9
^ means raise to power or power of
-3= the negative power
