Your coefficient is the number and your variable is the letter. So in this case your coefficients are 9 and 20 and your variables are x and y!
By definition, the area of a rectangle is given by:
A = w * l
Where,
w: width
l: long
Substituting values we have:
70 = w * (2w-4)
Rewriting we have:
70 = 2w ^ 2-4w
2w ^ 2 - 4w - 70 = 0
Solving the polynomial we have:
w1 = -5
w2 = 7
We take the positive root because it is a dimension.
w = 7 inches
Then, the length will be:
l = 2w-4
l = 2 (7) -4
l = 14-4
l = 10 inches
Answer:
its demensions are:
w = 7 inches
l = 10 inches
Answer:
The correct answer is: 
Step-by-step explanation:
According to the rule of BODMAS, division is done before addition.
So, in a + b ÷ c, we will first calculate, b ÷ c
Given b = 
= 
, c = 
.
So, 
= ÷
So, 
, as the numerator and denominator gets reversed as division is changed to multiplication.
So, 
.
Next the value of a to , where, 
, we get,
.
Opposite pairs of rays are 2 rays that have the same endpoint and extend in opposite directions. You want it to form a straight line.
Answer would be BD and BC
