Answer:

7 integers

Step-by-step explanation:

The inequality to solve is  3n^2-4

We can do algebra and solve this:

3n^2-4

If we solve 3n^2-48=0, we will get the intercepts. So:

3n^2-48=0\\3(n^2-16)=0\\n^2-16=0\\n^2=16\\n=4,-4

<em>Since, the inequality is less than, the solution set is all numbers between -4 and 4. So</em>

<em>-4 < n < 4</em>

<em />

<em>*note: -4 and 4 is NOT included, so the integers in the range are:</em>

<em>-3, -2, -1, 0, 1 , 2, 3</em>

<em>Which is </em><em>7 integers.</em>

ololo11 [35]

Answer:

option: b is correct.

( b.Yes, because both figures are rectangles and all rectangles are similar )

Step-by-step explanation:

Yes, the rectangle EFGH is a result of dilation of rectangle ABCD with a center of dilation at the origin.

Also The scale factor of the dilation is greater than one as the image is bigger than the pre-image i.e. there is a stretch.

The scale factor could be calculated by the ratuio of the sides of the image to the pre-image rectangle.

Rectangle ABCD: Its vertices have coordinates A(-3,3), B(3,3), C(3,0) and D(-3,0).

Now consider rectangle EFGH:  Its vertices have coordinates E(-4,4), F(4,4), G(4,0) and H(-4,0).

Hence the scale factor is:

\dfrac{EF}{AB}=\dfrac{EH}{AD}=\dfrac{FG}{BC}=\dfrac{HG}{DC}=\dfrac{4}{3}

Hence the scale factor is: 4/3.

Also

∠A=∠B=∠C=∠D=∠E=∠F=∠G=∠H=90°

( When a shape is dilated the two shapes are similar.And similar shapes have equal interior angles , corresponding sides are proportional ).

Hence option: b is correct.

( b.Yes, because both figures are rectangles and all rectangles are similar )

The Answer is 8 for, "The product of 32 and an unknown number subtracted from 435 is 179.
nirvana33 [79]
Putting this into an equation looks like this:

435 - 32<em>x</em> = 179

-32<em>x</em> = -256

<em>x</em> = 8


The answer <em>is</em> 8. Well done.
