L=w+2 and 2w+2l=44
substitute equation for length in perimeter equation
2w+2(w+2)=44
2w+2w+4=44
4w+4=44
4w=40
w=10
substitute width into length equation to get length
l=10+2
l=12
a=lw
a=12*10
a=120 cm^2
She used three eggs because 3 X 4 =12
Answer:
2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 0, 2 ], thus
f(b) = f(2) = -(2)² + 4)(2) + 2 = - 4 + 8 + 2 = 6
f(a) = f(0) = 2
average rate of change = 
= 
= 2
Yes, that is correct due to the distributive property. It states that you can distribute a number to another number.
for example: a(b + c) = ab + ac
in this case, you are distributing the -1 into the 2x + 10
-1(2x + 10)
(-1) * (2x) + (-1) * (10)
(-2x) + (-10)
-2x - 10
