${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:( - 5x {}^{2} \times 4x) - ( - 5 {x}^{2} \times 6 {x}^{2} ) - ( - 5 {x}^{2} \times 3)$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 20 {x}^{3} - ( - 30 {x}^{4} ) - ( - 15 {x}^{2} )$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: - 20 {x}^{3} + 30 {x}^{4} + 15 {x}^{2}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:30 {x}^{4} - 20 {x}^{3} + 15 {x}^{2}$

Answer: 3253

Step-by-step explanation:

Given : A test requires that you answer either part A or part B.

Part A consists of 7 true-false questions.

i.e. there are 2 choices to answer each question.

Now, the number of ways to answer Part A : $2^7=128$ (1)

Part B consists of 5 multiple-choice questions with one correct answer out of five.

i.e. there are 5 choices to answer each question.

Now, the number of ways to answer Part B : $5^5=3125$ (2)

Now, the number of different ways to completed answer sheets are possible= $128+3125=3253$ [Add (1) and (2) ]

AysviL [449]

Answer:

area will be

$16p {}^{2} - 9$

Step-by-step explanation:

after addition of 3, the length will be =》(4p+3)

after subtracting 3, the width will be =》(4p-3)

area = length × width

(4p+3) (4p-3)
16p^2 - 9

the area will be

$16p {}^{2} - 9$
