Answer:

If we are trying to find the area if the blue rectangle, the answer is 38x²-12x.

Step-by-step explanation:

Area of blue + white: (8x-1) × (6x) = 48x²-6x

Area of white: (5x+3) × (2x) = 10x²+6x

Area of just blue: (48x²-6x) - (10x²+6x) = 38x² - 12x

Answer:

a = 3

b = 2

c = 0

d = -4

Step-by-step explanation:

Form 4 equations and solve simultaneously

28 = a(2)³ + b(2)² + c(2) + d

28 = 8a + 4b + 2c + d (1)

-5 = -a + b - c + d (2)

220 = 64a + 16b + 4c + d (3)

-20 = -8a + 4b - 2c + d (4)

(1) + (4)

28 = 8a + 4b + 2c + d

-20 = -8a + 4b - 2c + d

8 = 8b + 2d

d = 4 - 4b

Equation (2)

c = -a + b + d + 5

c = -a + b + 4 - 4b+ 5

c = -a - 3b + 9

28 = 8a + 4b + 2c + d (1)

28 = 8a + 4b + 2(-a - 3b + 9) + 4 - 4b

28 = 6a - 6b + 22

6a - 6b = 6

a - b = 1

a = b + 1

220 = 64a + 16b + 4c + d (3)

220 = 64(b + 1) + 16b + 4(-b - 1 - 3b + 9) + 4 - 4b

220 = 60b + 100

60b = 120

b = 2

a = 2 + 1

a = 3

c = -3 - 3(2) + 9

c = 0

d = 4 - 4(2)

d = -4

Find the values of A, B, and C in the table.​
PilotLPTM [1.2K]

Answer:

A = 1

B = 2

C = below

Step-by-step explanation:

Zero is included in the second interval, therefore, A = 1 is a correct choice (A must be also less than 2 ).

B must be positive, so that, f(0) is above the x-axis, therefore, B = 2 is a correct choice.

f(1.5) is negative, this means that the function is <u>below</u> the x-axis, then, C = below.
