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 !
Answer:
1775
Step-by-step explanation:
5 x 5 = 25
50 x 5 = 250
5 x 300 = 1500
25+250=275
275+1500=1775
Answer:
-4
Step-by-step explanation:
4x+2y=...
1/2y × -4 = -2y

First compute the component form of vector u by subtracting its initial values from terminal values. 18-1=17, 6-(-12)=18. So u=(17, 18). Since v points in the opposite direction, and has a magnitude three times that of u, we multuply the u by -3 and get v=(-3*17, -3*18)=(-51, -54).
