Answer:
Step-by-step explanation:
= 2- 6*7 + 18*3 - 14
=2-42+54-14
=2 + 12- 14
= 14-14
=0

Answer:
a. (3x² - 2x - 5) units²
b. (x² - x) units²
c. (2x² - x - 5) units²
Step-by-step explanation:
a. Area of the frame = L*W
L = (x + 1) units
W = (3x - 5) units
Area of the frame = (x + 1)(3x - 5)
Apply distributive property
x(3x - 5) +1(3x - 5)
3x² - 5x + 3x - 5
Area of the frame = (3x² - 2x - 5) units²
b. Area of the picture = L*W
L = x units
W = (x - 1) units
Area of the picture = x(x - 1)
Apply distributive property
= x² - x
Area of picture = (x² - x) units²
c. Area of the frame that surrounds the picture = area of frame - area of picture
= (3x² - 2x - 5) - (x² - x)
= 3x² - 2x - 5 - x² + x (distributive property)
Add like terms
= 3x² - x² - 2x + x - 5
= 2x² - x - 5
Area of the frame that surrounds the picture = (2x² - x - 5) units²
Answer:
Rate = 12345.67 (cubic foot per second)
Flow rate = 49.3826
Step-by-step explanation:
Computation:
7.5 gallons = 1 cubic foot
1 gallon = 1 / 7.5 cubic foot
So,
8 billion gallon = (8 / 7.5) billion cubic foot
Rate = [8/(7.5 × 24123456 × 60 × 60)]
Rate = 12345.67 (cubic foot per second)
Flow rate = (12345.67/25,000) 100
Flow rate = 49.3826
