Which statements are true about David's work? Check all that apply. The GCF of the coefficients is correct. The GCF of the varia

Anon25 [30]

Answer:

The GCF of the coefficients is correct.

The variable c is not common to all terms, so a power of c should not have been factored out.

In step 6, David applied the distributive property.

Step-by-step explanation:

Given the polynomial :

80b⁴ – 32b²c³ + 48b⁴c

The Greatest Common Factor (GCF) of the coefficients:

80, 32, 48

Factors of :

80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80

32 : 1, 2, 4, 8, 16, and 32

48 : 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

GCF = 16

b⁴, b², b⁴

b⁴ = b * b * b * b

b² = b * b

b⁴ = b * b * b * b

GCF = b*b = b²

GCF of c³ and c

c³ = c * c * c

c = c

GCF = c

We can see that David's GCF of the coefficients are all correct

From the polynomial ; 80b⁴ does not contain c ; so factoring out c is incorrect

In step 6 ; the distributive property was used to obtain ; 16b²c(5b² – 2c² + 3b²)

Which is equivalent to (10)^(3/4)x?

ivann1987 [24]

Answer:

Option B is correct.

Step-by-step explanation:

$10^{(3/4)x}$

We need to write the above equation in square root form.

We know that 1/4 = $\sqrt[4]{x}$

So, $10^{(3/4)x}$ can be written as:

$(\sqrt[4]{10})^{3x}$

Option B is correct.

Rule: lines that are parallel have equal gradients.

Therefore y=-4/3x + b.

To find b, you must sub the point (6,2) into the equation y=-4/3x + b.

2= -4/3 x 6 + b
b=-10 (using algebra to solve)

Therefore y=-4/3x - 10.

Find the area of the composite figure will give extra 100 points out if answer is right and brainlyst

Vera_Pavlovna [14]

Answer:

Decompose the figure into two rectangles and add the areas.

Find the area of the entire rectangle and of the removed corner and subtract the areas.

Decompose the figure into three rectangles and add the areas.

Step-by-step explanation:

With all of these you can actually calculate the area of the composite figure, some of them are more easy and efficient than the other, for example dividing the composite area into three rectangles is not very efficient but will do the job, and the one where you decompose the area into two rectangles would be the best one, as well as the one where you find the area of the larger rectangle and the subtract from that the rectangle that is taken off in the right corner.
