Answer:

1. the value of x can equal 25

the shortest length can equal 7

the longest length can equal 30

2. 2x+2.1=7.5

Step-by-step explanation:

Given:

1.

A scalene triangle with sides y, 4y and x

and perimeter,p= 60cm

As per perimeter formula:

p= sum of all sides

Putting values we get

60=x+4y+y

60=x+5y

so correct options are

the value of x can equal 25

the shortest length can equal 7

the longest length can equal 30

2. An isosceles triangle with sides y=2.1, x and x

and perimeter,p = 7.5

As per perimeter formula:

p= sum of all sides

Putting values we get

7.5=2.1 + x +x

7.1=2.1+2x !

mr_godi [17]
8. To find the answer you can eather multipy it for each of the sides or you can add it 6 times once for each side
15\frac{1}{4} \times 6 \\ \\ 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4}
9. You basicly do the same thing as the previous problem but with the new numbers and you add each number 2 times

10. For are you multiply Base × Height So all you have to do is Multiply the 2 numbers shown together
2 \frac{1}{2} \times 5
11-12 Is the same but witb the new numbers

I hope this helps!
