Answer:
perimeter of rectangle= 2(4+X)
32=8+2x
32-8=2x
26=2x
26/2=X
14=X
perimeter of triangle=3×sides
20=3x
20/3=X
6.66=x
Answer:
Option 4
Step-by-step explanation:
You divide 1/2 by the whole problem
5x-15=20
and go from there its too long to explain but its option 4
Answer: 11
Students have both a brother and a sister
Step-by-step explanation:
I don't think probability should be used for this question because the answer is quite clear
So in a class of 25 students
5 students don't have a sibling
So 25-5=20
Total number of siblings=14+17=31 siblings in total
So 20 people have 31 siblings
31-20=11
So the answer should be 11
Cut only to ends of the triangle off then it will have a pentagon with the uncut shape
