Answer:
k=-9
Step-by-step explanation:
Given equation is
3k-5=(k+4)+3k
3k-5=k+4+3k
Adding -3k on both sides of equation we get
3k-5-3k=k+4+3k-3k
We know that 3k-3k=0
-5=k+4
Adding -4 on both side of above equation, we get
-5-4=k+4-4
-9=k
k=-9 which is the answer.
Answer:
6x²+ 9x- 15
Step-by-step explanation:
To find the area of a rectangle multiply length and width.
3(2x²+ 3x-5)
Use the distributive property to solve.
3(2x²)= 6x²
3(3x)= 9x
3(-5)= -15
The area would be
6x²+ 9x- 15
We need to first find the diagonal that moves along the base.
a²+b²=c²
12²+8²=c²
c²=208
c=√208
Now we have find the length for the answer.
(√208)²+14²=c²
c²=208+196
c²=404
c= 20.10 cm approx.
answer: C
Answer:
c and d
Step-by-step explanation:
4/8 = 1/2
a.1/2 =1/2 so it is not greater
b.1/4 < 1/2 = 2/4 so 4/8 is greater
c.7/8 > 4/8 so 7/8 is greater
d.3/5 3/5 = 6/10 1/2 = 5/10
3/5 > 4/8
