Answer:
6
Step-by-step explanation:
3(4 - 2)
Expand brackets.
3(4) + 3(-2)
12 + - 6
= 6
Here we have to find sum of -1000 and 1000.
The two numbers are equal and opposite in sign.
While adding a positive and a negative , we have to subtract.
so subtracting 1000 -1000, the answer is 0.
Another concept is when we add a number and its negative, we use this property,
a + (-a) =0
For example 2+(-2) = 2-2 =0
Similarly 1000 + (-1000) = 1000-1000 =0
This explains the concept .
Answer:
height = 7 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated using the formula
A = h(a + b)
where h is the height and a, b the parallel bases
here a = 6, b = 12 and A = 63, hence
× h × (6 + 12) = 63
h × 18 = 63
9h = 63 ( divide both sides by 9 )
h = 7
Answer: 28x+42y=3
Step-by-step explanation:
Given: The point (x,y) is equidistant from the points .
By distance formula the distance between is
Similarly, the distance between is
Since,
