The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
Are these simultaneous questions or like seperate ones?
Simultaneous:
4x -3(7x-4) = 12
4x - 21x + 12 = 12
-17x = 0
X = 0
Therefore y = -4
***
If it's a graph
x int: (3,0)
Y int: (0, -4)
Um idk if that's the answers you wanted but I hope it helped somehow??
Answer: 30.5
Step-by-step explanation:
30.5 times 4 equals 122
Answer:
28
Step-by-step explanation:
Area of a rectangle = width times length therefore the equation is 7 times 4 = 28.
