7-12(3+b)=31
7-36+12b=31
-29+12b=31
12b=31+29
12b=60
b=5
Greater=19
Smaller=3
Just use substitution
Answer:
18
Step-by-step explanation:
- -3a²-b³+3c²-2b³
- -3(2)²-(-1)³+3(3)²-2(-1)³
- -3(4)-(-1)+3(9)-2(-1)
- -12+1+27+2
- -11+27+2
- 16+2
- 18
Answer:
60 degrees
Step-by-step explanation:
EF and DC have lines through them indicating that they are equal in length, telling us that the figure is an isosceles trapezoid. Congruent base angles are a property of isosceles trapezoids, like isosceles triangles. This means that the base angles C and F will have the same measure. The measure of angle F is 60 degrees, therefore the measure of angle C will also be 60 degrees.
hope this helps :)
