Answer:
x=3
Step-by-step explanation:
You can solve by:
5x+7=-3x-31
adding 3x to each side:
8x+7=31
Subtract 7 from each side:
8x=24
Divide each side by 8:
x=3
That is your answer
Hope this helps!
Answer:
−2y3+4y2+18x+8
Step-by-step explanation:
Let's simplify step-by-step.
4(y2+2)+6x−2y3+12x
Distribute:
=(4)(y2)+(4)(2)+6x+−2y3+12x
=4y2+8+6x+−2y3+12x
Combine Like Terms:
=4y2+8+6x+−2y3+12x
=(−2y3)+(4y2)+(6x+12x)+(8)
=−2y3+4y2+18x+8
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (52 + 32)° = 180° - 84° = 96°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an exterior angle of the triangle, thus
y = 52° + 32° = 84°
z = 180° - (55 + 84)° = 180° - 139° = 41°
In conclusion
x = 96°, y = 84° and z = 41°
