Answer:
<em>8</em><em>+</em><em>s</em><em>+</em><em>n</em>
Step-by-step explanation:
Add s to 8=8+s
and add 3 to result=8+s+3
The answer would be 10.
6 + 5 = 11
11 x 9 = 99
This means 9(6+5) = 99
99 - 89 = 10
Answer:
The answer is 4:
2+2 =4
Step-by-step explanation:
Hi how are you?
Answer:
1,3 and 5
Step-by-step explanation:
1) -2(7x + 1) − 5(3x2 + 3x + 2)
= -14x - 2 - 15x^2 - 15x - 10
= -15x^2 - 29x - 12
2) (5x2 − 10x + 8) − (10x2 + 19x + 20)
= 5x^2 - 10x + 8 - 10x^2 - 19x - 20
= -5x^2 -29x - 12
3) (-7x2 − 21x + 13) − (8x2 + 8x + 25)
= -7x^2 - 21x + 13 - 8x^2 - 8x - 25
= -15x^2 - 29x - 12
4) (-19x2 − 4x - 7) + (4x2 + 25x − 5)
= -15x^2 + 21x - 12
5) (-17x2 + 2x − 3) + (2x2 − 31x − 9)
= -15x^2 -29x - 12
6) -2(4x − 15) − 3(5x2 + 7x + 6)
= -8x + 30 - 15x^2 - 21x - 18
= -15x^2 - 29x + 12
Answer:
RST= 105 degrees
Step-by-step explanation:
it would be 2(5x+15) + 2(4x+3) =360
10x+30+8x+6=360
18x=324
x=18
so RST=5x+15=5(18)+15=105
