Answer:
A. x=-15 and x=3
Step-by-step explanation:
|x+6|+8=17
|x+6|=9
-1(x+6)=9 x+6=9
-x-6=9 x=3
-x=15
x=-15
Answer:
The whole picture is an <em><u>supplementary</u></em> angle, which adds up to 180°
But angles 1 and 2 are <em>adjacent</em> angles. They dont overlap each other and share the same vertex or point of the same angle.
Your answer is <em>C. Adjacent angles</em>

Answer: 135 degrees
Step-by-step explanation:
First you now that ABD+DBC=180 degrees
Subsitute so you get: (5x+10)+(2x-5)=180
Solve:
(5x+10)+(2x-5)=180
=> 7x+5=180
=> 7x=175
=> x= 25
Plug in 25 :
ABD= 5*25+10=135
And there is your answer
1. To find the length of the edge, you will divide the total distance of 36 cm between the 4 edges that are shown.
36/4 = 9 cm per edge.
2. To find the surface area, find the area of one square (9 cm x 9 cm = 81 square cm), and multiply it by 6.
81 square cm x 6 = 486 square cm
486 square cm is the surface area.
the answer is x is equals to 2 or x is equal to -5 in the equation x square + 3x - 10 is equals to zero where after solving you get x square + 5 x - 2 x - 10 is equals to zero you factorise you get x (x + 5) - 2 (x + 5) is equal to zero then after solving x is equals to 2 or -5
