Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Let length of rectangle be "l"
Let width of rectangle be "w"
We know,
LENGTH is 2 MORE THAN WIDTH, we can write:
l = w + 2
Also, note the perimeter is the sum of all 4 sides of a rectangle, thus:
length + width + length + width
Now,
The perimeter is given as 72, so we can write:
l + l + w + w = 72
2l + 2w = 72
We have 2 equations that we need to solve and find the length (l).
The first equation is:
l = w + 2
Rearranging, we have:
w = l - 2
We put this into 2nd equation and find the value of l:
The length is 19 meters, the correct answer is C

(1.2 x 10 ^13) - (4 x 10 ^11)
10^13 = 10,000,000,000,000 put that in scientific notation to make it simpler do same for 10 ^11
10 x 10^13
(1.2 x 10 x 10^13) - ( 4 x 10 x 10^11)
now solve the first equasion
12,000,000,000,000 - 400,000,000,000
subtract
11,600,000,000,000
First you add 10 and 12 dollars to get 22 dollars then subtract the 14 dollars of the pizza to get 7 dollars left. Then add the other 18 given to them and your final answer adds up to 25 dollars in all. :)
Answer:
C. 0
Step-by-step explanation:
–4j^2 + 3j – 28 = 0
The discriminant is b^2-4ac if >0 we have 2 real solutions
=0 we have 1 real solutions
<0 we have 2 imaginary solutions
a = -4, b =3 c = -28
b^2 -4ac
(3)^2 - 4(-4)*(-28)
9 - 16(28)
9 -448
This will be negative so we have two imaginary solutions.
Therefore we have 0 real solutions
