Answer:
2.7
Step-by-step explanation:
1. AB/EF = P(ABCD)/P(EFGH)
4/5=16/P(EFGH)
P(EFGH)=5*16/4=5*4=20
2. V(old)=lwh =
V(new)=2*l*2*w*2*h =2³(lwh)=2³*V(old)= 8*3600=28800
3. A(old)=ab
A(new)=5a*5b=25ab=25A(old)
new area will be 25 times larger
Answer:
value of y = 95°
Step-by-step explanation:
=》128° + 72° + 65° + y = 360°
( because sum of all angles
of a triangle = 360° )
=》265° + y = 360°
=》y = 360° - 265°
=》y = 95°
i hope you got it.
EQUATION: 5x = 2x - 9
Add 9 to both sides
NEW EQUATION: 5x + 9 = 2x
Subtact 5x from both sides:
NEW EQUATION: 9 = -3x
Divide -x on bith sides
NEW EQUATION: -3 = x, or x=-3
