Answer:
Congruent
Step-by-step explanation:
Answer:
50cm squared
Step-by-step explanation:
Imagine the width is 'a'
Then the length will be 2a as it's twice as wide as it's long.
The formula for perimeter is 2(L+W)
If we subsitute the algebra/numbers in we get
P = 2(L+W)
30 = 2(2a+a)
30 = 2(3a)
30 = 6a
5 = a
a = 5cm
Then the area is the following
A = LW
A = 2a(a)
A = (2(5))(5)
A = 10(5)
A = 50cm squared
Given equation:
P=1500 (1.04)^x
When have to find x, when population, p=1900
Put value of P=1900 in above equation.
1900=1500(1.04)^x
Divide both sides by 1500
19/15=(1.04)^x
1.27=(1.04)^x
Take natural log.
ln(1.27)= ln(1.04)^x
ln(1.27)=x ln (1.04)
Divide both sides by ln (1.04)
x=6 years
Answer: 6 years
Step-by-step explanation:
Parallelogram
Reflect y=-1 ;x changes sign
Answer:
c
Step-by-step explanation:
since the line is going downward, it automatically means negative
and the first to answers mention adding which is positive, so A and B should be eliminated
since the slope is 72 (i dont feel like explaining why it is but trust me it is) that means the answer is c
