Answer: (6,2)
Step-by-step explanation:
Replace all occurrences of
y with 2x−10 in each equation.
−x+20=14
y=2x−10
Solve for x in the first equation.
x=6y=2x−10
Replace all occurrences of x with 6 in each equation.
y=2x=6
(6,2)
Point Form:
(6,2)
Equation Form:
x=6,y=2
Answer:
Step-by-step explanation:
we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)
so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.
the whole equation would be: 24+70+42= 136
so your answer would be B: 136.
hope this helps :)
B): x=8, y=8root2, z=16
c): x=4, y=12, z=8root3
The ones later one you can do by your self.
30 60 90 triangle side ratio: 1:root3:2
90 45 45 triangle side ratio: 1:1:root2
