Answers

Answer: See explanation

Step-by-step explanation:

Your question isn't really clear but let me help.

For Maths test,

Point earned = 30

Total point = 43

Percentage = 30/43 × 100 = 69.77%

Social studies test

Point earned = 85.

Total point = 124

Percentage = 85/124 × 100 = 68.55%

From the above, we can see that Jake scored a higher percentage in the Maths test.

Answer:

4x² + 12xy + 9y²

Step-by-step explanation:

Assuming you require the expansion

(2x + 3y)²

= (2x + 3y)(2x + 3y)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(2x + 3y) + 3y(2x + 3y) ← distribute both parenthesis

= 4x² + 6xy + 6xy + 9y² ← collect like terms

= 4x² + 12xy + 9y²

Answer:

[tex] {4x}^{2} + 12y + {9y}^{2} [/tex]

Step-by-step explanation:

[tex](2x + 3y) {}^{2} \\ {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} \\ = {(2x)}^{2} + 2 \times 2x \times 3y + {(3y)}^{2} \\ = 4 {x}^{2} + 12y + 9 {y}^{2} \\ hope \: it \: helps[/tex]

What is the multiplicative identity of -12/13

A.-13/12

B.1

C.0

D12/13

Answers

Answer:

The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.

Step-by-step explanation:

We know that when a number let say 'n' get multiplied by '1', it remains unchanged.

i.e.

n × 1 = n1 × n = n

The number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.

Given the number

-12/13

Multiply the number '-12/13' by '1'.

i.e.

-12/13 × 1 = -12/13

1 × -12/13 = -12/13

Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.
