The place where two equations intersect, has a certain value of y. This means that in the intersection point, the y-values of both expressions are the same, so y = y. Since y is also represented by the following equations, y = 4x and y = 2x - 2, the x-value of the intersection point is 4x = 2x - 2.
13 x 12 = 156 square inches
The total amount that all the angles inside the triangle equal is 180°.
So you can write an equation with the given
3x+5 + 2x+18 + 2x+17 = 180
Combine all like terms
7x + 40 = 180
subtract 40 from both sides
7x = 140
divide both sides by 7
x = 20
Then you plug that into the angles and find out how much each is
3x + 5
3(20) + 5
60 + 5
65
2x + 18
2(20) + 18
40 + 18
58
2x + 17
2(20) + 17
40 + 17
57
Hope this helps :)
Answer: BC=8 units
Step-by-step explanation:
So in this figure, this triangle, that is a parallelogram named DFCE , and one of their property three yeti you add learn you learned is that a parallelogram has like rectangle two sides per two that are parallel and have the same measure ( but you can also use the little lines that show who is the same as who ) in this one you can write an equality: CE=FD=4. Then there is the same two lines on the EB segment so EB=4 . Then we can write that BC= BE + EC
BC= 4+4
BC= 8 units
I’m not English so I tried explaining as simple as possible sorry if you didn’t understand :/
