Answer:
x = - 1
Step-by-step explanation:
Length ( l ) = 2x + 8 cm
Width / Breadth ( b ) = 2 cm
Area ( rectangle ) = 12 cm
Formula : -
Area ( rectangle ) = lb
12 = ( 2x + 8 ) ( 2 )
Divide 2 on both sides,
12 / 2 = ( 2x + 8 ) ( 2 ) / 2
6 = 2x + 8
2x + 8 = 6
2x = 6 - 8
2x = - 2
x = - 2 / 2
x = - 1
<span>-2(-6+5k)-1
Use distributive property(Multiply the -2 by the -6 and 5k)*Note: When you multiply a negatavie number by another negative number, it creates a positive number.
12 - 10k - 1
Subtract 1 from 12.
Final Answer: 11 - 10k
This equation cannot be simplified down any longer.</span>
answer:
slope: -2/3
step-by-step explanation:
y=mx+b
m represents the slope, and b the y-intercept.
rearrange: 9x= -6y+18
---> -6y= -9x-18
divide all terms by -6.
-6y/-6= -9/-6x-18/-6
y= 3/2x+3 (slope/intercept form)
m= 3/2
---> 1/3/2= -2/3
Answer:
I think it's the first one.
Step-by-step explanation:
cos50 = x/53
0.64 = x/53
x = 0.64×53
= 33.92
