Answer:
35/18
Step-by-step explanation:
Answer:
Part A-only the congruence of the rectangles
Step-by-step explanation:
Part B-C-both the congruence of the triangles and the congruence of the rectangles
7=x^2+20x+82
0=x^2+20x+75
What adds to 20 and multiplies to 75? 5 and 15.
x^2+5x+15x+75
x(x+5) 15(x+5)
(x+15) (x+5)
Zeroes are x= -5 and x= -15
Answer:
No real roots.
Step-by-step explanation:
Discriminant = b^2 - 4ac ( for the equation ax^2 + bx + c = 0)
Here it is 4^2 - 4*1*8
= `6 - 32
= -16.
This is negative so there are no real roots.
Answer:
x = 10
Step-by-step explanation:
Here, we are tasked with calculating the value of x.
To do this, we need the picture of the wordings given in the question.
please check the attachment for a pictorial representation.
Now the theorem to use is that , the exterior angle of a triangle is equals the sum of the two opposite interior angle.
Thus, mathematically;
3x + 11 + 3x + 15 = 10x -14
6x + 26 = 10x -14
10x-6x = 26 + 14
4x = 40
x = 40/4
x = 10
