5x + 2(3x + 1) < 3 Distribute 2 into (3x + 1)

5x + (2)3x + (2)1 < 3

5x + 6x + 2 < 3 Combine like terms(terms that have the same variable and power/exponent)

11x + 2 < 3 Your answer is B

X^2 -(y^2-x-1). >>simplify
=x^2+ (-4)(y^2)+(-4)(-x)+(-4)(-1). >>>> distribute
= x^2 -4y^2 + 4x +4 >>>>answer

Please help if you can

Arisa [49]

Answer:

Option D

Step-by-step explanation:

Formula to be used,

Scale factor = $\frac{\text{Dimension of the image rectangle}}{\text{Dimension of the original}}$

By this formula,

$\frac{7}{2}=\frac{\text{Length of the dilated rectangle}}{\text{Length of the original rectangle}}$

$\frac{7}{2}=\frac{L}{22}$

L = $\frac{7\times 22}{2}$

= 77 inches

Similarly, width of the the dilated rectangle = $\frac{7}{2}\times 10$

= 35 inches

Perimeter of the new rectangle = 2(Length + width)

= 2(77 + 35)

= 224 inches

Option (D) will be the correct option.

Name three orders Pairs that are solution of the system of inequalities shown below .

Schach [20]

Answer:

Step-by-step explanation:

the 2nd line can be rewritten as y < x-3

So, any value that is less than both 4x+4 and x-3 will work

Pick any value you want for x, and figure y possibilities

x=0; x-3=-3, 4x+4=4, so y<-3 ... (0,-5) will work

I'm sure you can now come up with other pairs.
