You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.

3 (x2 + 10x + 25)

Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2

Answer:

  • a) AB = 10 units
  • b) Midpoint is (2, 6)

===================

<h3 /><h3>Given</h3>

  • Points A( - 1, 10) and B(5, 2)

<h3>To find</h3>

  • a) The length of AB
  • b) The midpoint of AB

<h3>Solution</h3>

a) Use the distance formula:

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substitute the coordinates and calculate:

d=\sqrt{(5-(-1))^2+(2-10)^2} =\sqrt{6^2+(-8)^2} =\sqrt{36+64} =\sqrt{100} =10

The distance is AB = 10 units

b) Use midpoint formula and find x and y- coordinates of this point:

x= \cfrac{x_1+x_2}{2}    and    y= \cfrac{y_1+y_2}{2}

Substitute coordinates and find the midpoint:

x= \cfrac{-1+5}{2} =2  and  y= \cfrac{10+2}{2}=6

The midpoint is (2, 6)

Answer:

The above triangle is an isosceles triangle....

Reason

As we can see AB and DE are parallel to each other

As angle ABC is 80 degree

Therefore BCE is too 80 degree (as they both are alternate to each others)

Hence angle DCB is a 50 degree because in the straight DCE we have angle BCE as <u>80 </u><u>degree</u><u> </u>and Angle ACD as <u>50 degree</u>

Since a straight line has <u>180 degree</u> therefore the remaining angle ACB is 50 degree(180-80-50)

Now in triangle BAC. Angle C is 50 degree and Angle B is 80 degree, since the total angle of a triangle is 180 degree therefore A is 50 degree that is angle BAC is 50 degree(180-50-80) .

Hence here we see that two opposite sides have same angle that is the reason its a ISOSCELES triangle

Factor completely 4x4 − 24x3 + 36x2.
riadik2000 [5.3K]
The answer:  "4x² (x − 3)(x − 3)" ;  or, write as:  "4x² (x − 3)² " .
_________________________________________________
Explanation:
__________________________________________________

Given:  " 4x⁴ − 24x³ + 36x² " ;   The least common factor is:  4x² ;

since the least common NUMBER as a factor is "4";  and the least common "variable" as a factor is "x² " ;
_____________________________
  4x⁴ − 24x³ + 36x²   = 4x² (x² − 6x + 9) ;

Factor the:  "(x² − 6x + 9)" ;

   (x² − 6x + 9) = (x − 3)(x − 3) ;

Rewrite:  "4x² (x − 3)(x − 3)" ;  or, write as:  "4x² (x − 3)² " .
