Answer:
<h2> 4(-1+2-3+4-5+6-7+......+1000) = 2000</h2>
Step-by-step explanation:
-1+2 = 1
-3+4 = 1
-5+6 = 1
and so on till -999+1000 = 1
1 .... 1000 - these are 1000 numbers, so
1000:2 = 500 pairs with sum equal 1
4(500•1) = 4•500 = 2000
Answer:
The bush after the two weeks was 14.4 inches tall
Step-by-step explanation:
Let
x ----> bush height after two weeks
we know that
The bush height after two weeks is equal to multiply the height when it was first planted by 1.20
so
Perimeter=120
ED=x (length)
FE=4x (breadth)
Perimeter of rectangle= 2(l+b)
Given,
2(x+4x)=120
2x+8x=120
10x=120
x=120÷10
x=12
Therefore, value of x is 12
