Answer:
subtraction property for sure its that
Answer:
Yea that problem is a bit confusing,
2y should be double of what y is, which is 4x+5
Then 2y says 8x+15, when it should be 8x+10.
I feel bad cause I am sure the teacher is wrong on this, he/she had probably made a typo, or you made a typo, but that's ok! We all make typos!
The teacher would be extra rude if they marked you wrong on this, cause the question itself is not written "properly"
Simple,
1.) A vertical angle, is an angle directly across another angle. Thus, <2 and <5 are vertical angles.
2.)This is another pair of vertical angles, thus, m<4 is 53.
3.)Since m<1 is 50
You have the m<4 which is 50. You already have m<3 which is the right angle, 90.
Thus, 90+50=140
You know a line is supposed to be 180 degrees. So take,
180-140=40
Thus, the m<5 is 40.
1) 5t^2 (1 + 6t)
2) 4x^3y^5 (5x + 2y)
3) (5r + 6x)(5r - 6x)
4) (x + 10)(x - 10)
5) (x - 3)^2
6) (x -5)(x - 3)
7) 3(16r^3 + 9)
8) 8(c^3 + 8d^3)
9) (2r - 125)(4r^2 + 250r + 15625)
10) (c + 3)(c - 1)
