1/2 * 5 = 2.5.
You would need 2.5 boxes to build 5 birdhouses.
Answer:
Step-by-step explanation:
The far right side of the triangle is 17 cm, which is the height.
The base would be 34 minus 17 because whole length of the rectangle is 34 and the triangle covers all but 17 of it.
So then you would take 1/2 of 17.
Then multiply it by 17 to get 160.5
7x-15=-2
Move -15 to the rigjt side,
7x=-2+15
7x=13
Divide both sides by 7,
7x/7=13/7
x=13/7
Answer: Subtract 6 from both sides. Then, one would get 3x=15. Divde by 3 on both sides. x=5.
Step-by-step explanation:
It will be 5 because 4^2+3^2= 16+9=25 and then square root of 25=5
