Answer:

(10x+4x^2+13)

Step-by-step explanation: 10 and 3 do not have a variable therefore they go together (both being positive you add). 2x, 2x, and 6x have the same variable, being positive you add. 4x^2 is the only number with the x^2 variable and stays by itself due to no others.

In the diagram, mZXYZ = 115° and mZWXY = 45°.
Allushta [10]

Step-by-step explanation:

mXYZ+mXYW=180°(being straight angle)

mXYW =180-115

mXYW=65

now,

mXWY+mWXY+mXYW=180°(sum of angle of triangle)

mXWY=180-110

mXWY=70°

hope it helps.

Plums are $3.25 for 2 pounds, i need 4 pounds. how much will it cost
olasank [31]
<u />\frac{3.25}{2lbs} = \frac{x}{4lbs}  \\  \frac{3.25}{2} *  \frac{2}{2} = \frac{x}{4}  \\  \frac{3.25 * 2}{2*2} = \frac{x}{4}  \\ 3.25*2 = x \\ x = 6.50
It will cost $6.50 for four pounds of plums.

Hope this helps!

Subject Algebra 1
Mashutka [201]

Answer:

10x^{2}-34

Step-by-step explanation:

Because we are told equivalent expressions for y and z we can plug those in to 2(y+z).

2((3x^{2}+x^{2}-5)+(x^{2}-12))

Then simplify by combining like terms of the expressions. Values ending in x^2 can be combined with each other.

2(5x^{2}-17)

Now we can distribute the 2 by multiplying each value in the parentheses by 2.

10x^{2}-34
