Step-by-step explanation:
The answer is 14 because a negative number multiplied by another negative number is positive. So (-7)*(-2) is 14.
Step-by-step explanation:
5x-6+7x+18=180
12x=180+6-18
12x=168
168÷12=14
X=14
for y
3y+11=7x+18(7×14+18)
3y+11=116
3y=116-11
3y=105
y= 35
Has to be greater than 90 degrees.
