Answer: 3x+3, 5x+40, 4x+24
Answer:
15units
Step-by-step explanation:
Area=pi×r², where r is the radius.
706.5=3.14×r²
r²=225
r=15units
Number = 42
50% of 42
= 50/100 × 42
= 21
Increased number = 42 + 21 = 63
Answer:
Infinitely many solutions.
Step-by-step explanation:
1.5 x 5 x 2.6 / 2 would be the equation for the Triangle, because we can look for the area if it was a square and divide it by two, 1.5 x 5 = 7.5 and 7.5 x 2.6 = 19.5, now all we need to do is divide it by 2, because the equation I used would be used to find the area of a rectangular prism, and because a triangular prism is half of a rectangular prism, we just need to divide 19.5 by 2, so... 19.5 /2 = 9.75
