Answer:
Perimeter: 52 Area: 181-16i?
Step-by-step explanation:
Perimeter
The formula for perimeter is 2l+2w, so you plug in the binomials they give you:
2(11-4i)+2(15+4i)
expand:
22-8i+30+8i
combine like terms (which cancels out 8i and -8i):
22+30=52
Area
"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.
Here's what I did to get 181-16i, in any case:
The formula for area is l*w, so I plugged in the numbers:
(11-4i)(15+4i)
expanded:
165+44i-60i-16i*i
and combined like terms:
181-16i
*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.

The planet mercury makes its circuit around the sun in 88 days. Venus takes 225 days to complete it's circuit. Venus's travel time is what percent of Mercury's travel time?
Answers
Answer:
255.682%
Step-by-step explanation:
From the above question:
The planet mercury makes its circuit around the sun in 88 days.
Venus takes 225 days to complete it's circuit.
Venus's travel time is what percent of Mercury's travel time?
This is calculated as:
(Number of days Mercury take to complete it's circuit/Number of days Venus takes to complete it's circuit) × 100
= 225/88 × 100
= 2.5568181818181817 × 100
= 255.68181818%
Approximately = 255.682%
Venus's travel time is 255.682 percent of Mercury's travel time
Which steps should be used to compare the fractions 2/9 and 5/6
1) Find a common numerator.
1) Add the numerators and denominators to determine which sum is larger.
1)Use the "greater than" symbol to show which denominator is larger.
1) Multiply the first fraction by 2/2 and the second fraction by 3/3
Answers
Answer:
turn them into equivalent fractions with a common denominator.
2/9 and 5/6 common denominator that we can use is 18.
what you do to the denominator must be done to the numerator.
so to get from 9 to 18 we multiply by 2. this needs to be done to the numerator.
2 X 2 = 4 the fraction should now be 4/18
to get from 6 to 18 we multiply by 3 again do same to numerator. should now be 15/18
now compare the two
4/18 and 15/18. now we know that 5/6 is bigger than 2/9.

1. JK = LM, JKM = LMK -> This is given information.
- From this given information, we know:
1. 2 congruent sides
2. 2 congruent angles
Now all we have to do is find one more side to prove SAS triangle congruence.
Next, we notice that the side MK is used by both the triangles we are trying to prove congruent. So we can say "MK = MK" by the reflexive property. (Since they share the same side).
Then, we can say triangle JMK is = triangle LKM because of SAS congruence.
*Please note the = signs I used should be actually congruence signs*

Answers
Answer:
The graph represents the system of inequalities y ≤ -3x + 2 and y ≤ -x + 2 ⇒ C
Step-by-step explanation:
From the given figure
∵ The direction of each line is to left
∴ The slopes of the lines are negative
∵ The slope of the line is the coefficient of x
∴ The coefficient of x in each inequality is negative ⇒ (1)
∵ The two lines intersect the y-axis at the point (0, 2)
∴ The y-intercept of the two lines is (0, 2)
∵ The y-intercept is the numerical term in the equation
∴ The numerical term in each inequality is 2 ⇒ (2)
∵ The two lines are solids
∵ The shaded area of each one is under the line
∴ The sign of inequality in both equations is ≤ ⇒ (3)
→ Look at the answer and find which one has the 3 conditions above
∵ y ≤ -3x + 2 and y ≤ -x + 2
∴ m = -3 and m = -1 ⇒ negative coefficients of x
∴ b = 2 ⇒ numerical term
∵ The sign of inequality is ≤
∴ The graph represents the system of inequalities y ≤ -3x + 2 and y ≤ -x + 2
