Answer:

(2x - 1)(2x + 1)(x - 7)

Step-by-step explanation:

We use grouping to factor.

Step 1: Group 1st 2 terms together and factor

4x³ - 28x²

4x²(x - 7)

Step 2: Group last 2 terms together and factor

-x + 7

-1(x - 7)

Step 3: Combine

(4x² - 1)(x - 7)

Step 4: Factor out quadratic

(2x - 1)(2x + 1)(x - 7)

Let's solve ~

$\qquad \sf \dashrightarrow \: 10x + 30 = 90$

[ according to given figure ]

$\qquad \sf \dashrightarrow \: 10x = 90 - 30$

$\qquad \sf \dashrightarrow \: 10x = 60$

$\qquad \sf \dashrightarrow \: x = 60 \div 10$

$\qquad \sf \dashrightarrow \: x = 6 \degree$

Correct choice is D

Answer:Jake's total cost is $22.05

Step-by-step explanation:

The initial price of the sweater is $30. The store is having a sell that will reduce the price by 30%. This means that there is a reduction in the original amount of the sweater by 30% which is expressed as

30/100 × 30 = $9

The new price of the sweater would be 30 - 9 = $21

Since a sales tax of 5% will be added to the final purchase price, the value of the tax would be

5/100 × 21 = 0.05×21 = $1.05

Jake's total cost would be

21 + 1.05 = $22.05
