Let's solve for c.
x2+18x+c=25+c
Step 1: Add -c to both sides.
x2+c+18x+−c=c+25+−c
x2+18x=25
Step 2: Add -x^2 to both sides.
x2+18x+−x2=25+−x2
18x=−x2+25
Step 3: Add -18x to both sides.
18x+−18x=−x2+25+−18x
0=−x2−18x+25
Step 4: Divide both sides by 0.
00=−x2−18x+250
c=−x2−18x+250
Answer:
c=−x2−18x+250
For this case we have the following vector:
v = 2 * (cosine (45) i + sine (45) j)
Rewriting we have:
v = 2 * (cosine (45) i + sine (45) j)
v = 2 * ((0.707107) i + (0.707107) j)
v = (1.414214) i + (1.414214) j
Answer:
the vector of length 2 making an angle of 45 with the x-axis is:
v = (1.414214) i + (1.414214) j
(2x +3x) + (-5+10) = 5x +5 combine by terms
Lets divide this prism into two parts. The bottom part has dimensions of 15mm length x 5mm width x 7mm height.
The bottom is 15x5x7 = 525 cubic mm.
The top part has dimensions of 9mm length (I got this by subtracting the 3mm on each side that the top is shorter than the bottom.. 15-3x2) x 5mm width x 3mm height.
The top is 9x5x3 = 135 cubic mm.
Added together ... 525 + 135 = 660 cubic mm = the total area of the prism.
Hope this helps
Answer:
x+y
Step-by-step explanation:
Let's pretend the value of the crayon's is 'y'. The value of the markers is 'x'. If we add them together, we get x+y. This is because we do not know the value of each variable.
Hope this helps! Have a nice day <3
