Answer: 31.5 square units
Explanation:
The area of the rectangle is length*width = 7*3 = 21 square units
The area of the triangle is 0.5*base*height = 0.5*7*3 = 10.5 square units
The combined area is 21+10.5 = 31.5 square units
Answer:
only -7
Step-by-step explanation:
Just plug them in.
so for x=-7 So this one is extraneous
Then if you plug -3 in you get 1 = 1 so this one is not extraneous. if you need me to work this one out let me know.
Let height of house be x.
Oak tree = 120 + x
Also given,
Oak tree = 2.5x
120 + x = 2.5x
1.5x = 120
0.3x = 24
3x = 240
x = 80
Hence, the height of the house is 80 ft.
