Answer:
591
Step-by-step explanation:
“Let the width of the garden =x meter
Then length=(x+4) meter
Half perimeter =36 m
So perimeter of garden =(2×36)=72 meters
According to the question
⇒2(l+b)=72
⇒2(x+x+4)=72
⇒2x+2x+4=74⇒4x=64⇒x=16 meters
Hence,the width of the garden =16 meters
The length of the garden =(16+4)=20 meters”
Answer:
Simplify.
(2x2 - 5x + 3) - (-x2 + 4x - 5)
the answer is -7x +12
Step-by-step explanation:
the question can be solved using BODMAS law
from Simplify.
(2x2 - 5x + 3) - (-x2 + 4x - 5)
opening the bracket
4-5x + 3 + 2x - 4x + 5
collecting the like terms we have;
12-7x
therfore ; -7x + 12
1. 81 1/2 = 163/2
2. 32 1/5 - 64 1/3 =
483/15 - 965/15 =
-482/15 or -32 2/15
3. 16 1/4 = 65/4
4. 49 1/2 + 27 1/3 =
99/2 + 82/3 =
297/6 + 164/6 =
461/6 or 76 5/6
Answer:
2.5 x 10^{-2] = 0.025
Step-by-step explanation:
If you mean standard DECIMAL form, then you move the decimal point 2 places to the left because of the negative power of 10:
