First of all 1+2=3 which leads to 6:3x=1 3x=6:1 3x=6 X=2
Answer:
-89
Step-by-step explanation:
-89
-89= 10(-7) - 19 -----------> -70 - 19
Area = \frac{a X p}{2}
Area = apothem times perimeter over 2
Let’s write it simply, that helps us solve it easier.
6x^2+4x+8
Now, insert 7 in place of x.
6(7)^2+4(7)+8
Now, multiply.
42^2+28+8
Solve for exponents.
1,764+28+8
Add.
1,792+8
1,800
Hope this helps!
Supplementary angle = 180
180 - 51 = x
x = 129
C) 129 degrees is your answer
hope this helps
