Answer:
140
+168xy+49
+280x+154y+105
Step-by-step explanation:
(−14x+−7+−7y)(−10x+−15+−7y)
=(−14x)(−10x)+(−14x)(−15)+(−14x)(−7y)+(−7)(−10x)+(−7)(−15)+(−7)(−7y)+(−7y)(−10x)+(−7y)(−15)+(−7y)(−7y)
Answer:
x = -.25
Step-by-step explanation:
x - 3.75 = -4
x = -.25
I disagree because a rational number doesn't terminate or repeat. That would be an irrational number.

Answer:
Step-by-step explanation:
Check the attached diagram... since they are parallel lines, those angles should be equal. now as per the theorem of opposite angles, (3x + 10)° should be equal to 70° .
(3x + 10)° = 70°
3x = 60°
x = 20
Answer:
x = 4
y = -7
Step-by-step explanation:
y = -2x + 1
4x + y = 9
4x + y = 9
4x + (-2x + 1) = 9
4x - 2x + 1 = 9
2x + 1 = 9
2x = 9 - 1
2x = 8
x = 8/2
<u>x = 4</u>
4x + y = 9
4(4) + y = 9
16 + y = 9
y = 9 - 16
<u>y = -7</u>
