Answer: 43.07
Step-by-step explanation:
A. 40x^2 + 240x + 200
Shape: Rectangle
Formula: A = LW
A = (10x + 10)(4x + 20)
= (10x)(4x) + (10x)(20) + (10)(4x) + (10)(20)
= 40x^2 + 200x + 40x + 200
= 40x^2 + 240x + 200
————————————————————-
2. 57,600 ft^2
Width:
4x + 20 = 160
4x = 140
x = 35
Plug-In:
10x + 10
10(35) + 10
350 + 10
360 = Length
————————————-
A = LW
A = 360 • 160
A = 57,600 ft^2
The answer is either B or D
Answer:
b. only reason is correct
2.05 kg=2.05 ×1000 g
=2050 g
so the Assertion is incorrect
For a variable to vary directly to another is telling you to set up a proportion
v/g = v/g
36/4 = v/11
4v = 396
v = 99
