Answer: the expanded form is 2x^2+13x+15
Explanation:
2x^2 +3x +10x +15
2x^2+13x+15
Could use a diagram, but just remember<span> </span>collinear points<span> all lie on a straight line, in the three dimensional world, when a set of </span>points<span> all lie on the same plane, they are called </span>coplanar<span>. </span>
Answer:
Simplifying
2x + -15 + x + -5 = 148
Reorder the terms:
-15 + -5 + 2x + x = 148
Combine like terms: -15 + -5 = -20
-20 + 2x + x = 148
Combine like terms: 2x + x = 3x
-20 + 3x = 148
Solving
-20 + 3x = 148
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '20' to each side of the equation.
-20 + 20 + 3x = 148 + 20
Combine like terms: -20 + 20 = 0
0 + 3x = 148 + 20
3x = 148 + 20
Combine like terms: 148 + 20 = 168
3x = 168
Divide each side by '3'.
x = 56
Simplifying
x = 56
The 4th one is the answer
Answer:
Step-by-step explanation:
2(4z+3+3z)=174
7z+3=174/2=87
7z=87-3=84
z=84/7=12
WX=3z=3×12=36 units
