Answer:
2nd option: the lowest point on the graph is (-2, -2). this is where both sides of the parabola converge. from this point, both lines go up. this means the vertex is a minimum.
As we can notice the shape is a Pentagon. A Pentagon's angles should add up to 540. So we can use simple addition and subtraction to solve.
121 + 108 + 102 + 100 = 431
540 - 431 = 109
109 should be your answer

Step-by-step explanation:
- <u>Solve equation to find answer(s)</u>

Combine: 6z - 3z = 3z
![\bold{3z-7=-2+3}](https://tex.z-dn.net/?f=%5Cbold%7B3z-7%3D-2%2B3%7D)
Add: -2 + 3 = 1
![\bold{3z-7=1}](https://tex.z-dn.net/?f=%5Cbold%7B3z-7%3D1%7D)
Add 7 to both sides:
![\bold{3z-7+7=1+7}](https://tex.z-dn.net/?f=%5Cbold%7B3z-7%2B7%3D1%2B7%7D)
Simplify:
![\bold{3z=8}](https://tex.z-dn.net/?f=%5Cbold%7B3z%3D8%7D)
Divide both sides by 3:
![\bold{\frac{3z}{3}=\frac{8}{3}}](https://tex.z-dn.net/?f=%5Cbold%7B%5Cfrac%7B3z%7D%7B3%7D%3D%5Cfrac%7B8%7D%7B3%7D%7D)
Simplify:
![\bold{z=\frac{8}{3}}](https://tex.z-dn.net/?f=%5Cbold%7Bz%3D%5Cfrac%7B8%7D%7B3%7D%7D)

Answer:
120cm
Step-by-step explanation:
A triangle has a perimeter of 120 cm and two sides of 30 cm and 40 cm. Calculates the area. A right triangle has a cathetus of 10 cm and the hypotenuse 26 cm.
