Answer:

$2500

Step-by-step explanation:

CA=p(1+MR÷1200)

4000=p(1+180×4÷1200) 15 yrs =15×12=180 month

4000=1.6p

p=4000÷1.6

p=2500

-8(4+9x)=7(-2-11x)<br> please help me solve this i have no clue and this is my math homework
Aloiza [94]

Distributive property

-8*4=-32          -8*9x=-72x

-32-72x=7(-2-11x)

7(-2)=-14      7(-11x)=-77x

-32-72x=-14-77x

Combine Like Terms

-32+14=-18       -77x+72x=-5x

-18=-5x

Divide both sides by -5 and theres your answer

Hi, help will be appreciated

Answer:

KM=9

JK= 12.69

Angle JKM=45 degrees

ML=18.97

MKL=60 degrees

Angle L=30 degrees

Step-by-step explanation:

Triangle JKM is a 45, 45, 90 degree triangle so that means both side lengths are equal and the hypotenuse is square root of 2 times a side length. This means, KM will be equal to 9 and JK will be equal to 9 times square root of 2. For triangle KML, you know that the triangle is a 30,60,90 degree triangle. This means the hypotenuse is a^2+b^2=c^2 where c is the hypotenuse.  Since you know that a is 9 and c is 21, plug them into the equation to get 81+b^2=441. Subtract 81 from both sides to isolate b^2 to get 360. b^2 = 360. Then find the square root of 360 which is about 18.97. Therefore, b or ML is equal to 18.97. Also, because we know that MKL is a 30, 60, 90 triangle, we know that angle MKL is equal to 60 degrees. Because we know the angles of MKL(60) and KML (90), we do 180-90-60 to find angle L. Simplify 180-90-60 to 30 and that means that angle L is equal to 30 degrees.  Since we know that JKM is a 45, 45, 90 degree triangle, we know that JKM is equal to 45 degrees. Therefore, KM is equal to 9, JK is equal to 9 times square root of 2 or 9 times 1.41 which is 12.69. Angle JKM is 45 degrees, ML is 18.97, angle MKL is 60 degrees, and angle L is 30 degrees.

7(8i+9) (Show work please)
ivanzaharov [21]
Using the distributive property, you’ll get the equation 56i+63.


You’ll distribute (multiply) 7 to 8i, and 7 to 9
