The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where x represents the small

er integer. Which equation can be factored and solved for the smaller integer?

For this case we have the following equation:
 x (x + 1) = 72

 We can rewrite the expression.
 For this, we first make distributive property:
 x ^ 2 + x = 72

 Then, we add -72 on both sides of the equation:
 x ^ 2 + x - 72 = 72 - 72

 Rewriting we have:
 x ^ 2 + x - 72 = 0

 This is the equation that must be factored and solved for the smallest integer.

Answer:

The smallest integer is 8

Step-by-step explanation:

x(x+1)=72

applying distributive law in Right hand side and subtracting 72 from both hand sides we get

x^2+x-72=0

Now we are required to find the factors of 72 , such that their difference is 1. The factors are 8 and 9 and 9-8=1. Hence they satisfies our requirements. Now we split the middle term like

x^2+9x-8x-72=0

taking x and 8 as GCF from brackets

x(x+9)-8(x+9)=0

(x-8)(x+9)=0

Hence  

if (x-8)=0 ; x=8

if  (x+9)=0 ; x=-9

Hence our answer is 8 and 9

How do the angle measures of polygon ABCD compare with the angle measures in the reflected image? How do the side lengths compar
Tresset [83]

The measures of the angles ABCD are the same as the measures of the angles that is corresponding based on the reflected images.

<h3>How to show that the angles are equal</h3>

Based on the fact that this is a reflection, the angles would be equal measures.

What this means is that there is a preservation of the of the reflected image. This is the same logic for the length of the sides.

The reflection is known to be a rigid type of transformation that is known to have its angles and sides preserved.

Find the equation of the line that passes through the point (−3, −4) and is parallel to the line that passes through the points
Dimas [21]

Answer:

y = -\frac{1}{3}x - 5

Step-by-step explanation:

To write the equation of a line use the point slope formula y - y_1 = m(x-x_1). Find m by using the slope formula with the points.

m = \frac{y_2-y_1}{x_2-x_1} = \frac{1--3}{-5-7} =\frac{4}{-12} =-\frac{1}{3}

Since the line is parallel, it will have the same slope.

Substitute m = -1/3 and (-3,-4).

y --4 = -\frac{1}{3}(x --3)\\y + 4 = -\frac{1}{3}(x+3)\\y +4 = -\frac{1}{3}x - 1\\y = -\frac{1}{3}x - 5
