Answer:
Step-by-step explanation:
Step 1: Open the brackets
Step 2: Bring the similar variables together
Step 3: Simplify by adding/subtracting the coefficients of the similar variables
Step 4: Rearrange as required.
We know all the side lengths so can use law of cosines. a=90, b=55, and c=50.
2500=8100+3025-2(90)(55)cos(C)
cos(C)=.8712
C=arccos(.8712)=29.4 degrees
Answer: 8 3/4
Step-by-step explanation:
3x(4x-5+3); where x is 1/2
Substitute the value 1/2 with x
3 1/2 (4 1/2 - 5+3)
7/2 (9/2 -2)
7/2 (5/2)
35/4 = 8 3/4
Answer:
2 miles = 3,520 yards
first we need to find how many yards she's walked already :
400×5=2,000 yards
now subtract :
3,520-2,000= 1,520 yards
Keisha needs to walk 1,520 more yards to complete 2 miles
hope this helped
