Answer:

d) 7(30 + 9) = 7(30) + 7(9)

Step-by-step explanation:

Distributive method:

Here given:

Among the option's:

1st option (7 + 3) (7 + 9) is wrong, changes final answer.

2nd option (7 × 30) + 9 is wrong, changes final answer.

3rd option 39 × 7 shows commutative property of multiplication.

4th option show distributive method.

Answer: -342.7074

Step-by-step explanation: first multiply 7(-2.655), which is -18.585. since only one of the numbers is negative, the product will also be negative. multiply -18.585 by 18.44. this is equivalent to -342.7074.

Step-by-step explanation:

answer is 11 or d

squareroot 25=5

so 5-5=0

3²=9

so 9+2=11

Answer:

I believe its C, I could be wrong tho

Hello,

[tex]( {c}^{2} + {d}^{2} ) - 2( {c}^{2} - {d}^{2} )[/tex]

[tex] = (( - 2) {}^{2} + 2 {}^{2} ) - 2(( - 2) {}^{2} - 2 {}^{2} )[/tex]

[tex] = (4 + 4) - 2(4 - 4)[/tex]

[tex] = 8 - 2 \times 0[/tex]

[tex] = 8[/tex]

Answer:

d or 16

Step-by-step explanation:

(-2²+2²)-2(-2²-2²)

-2(-4-4)

8+8=16

Answer: D

Step-by-step explanation:

Follow the PEMDAS rule.
It’s not A, because when you solve 2^2 and sq rt of 4, the square exponent and the square root cancels out, so it’s simply 2 x 4. Then you follow by doing division and multiplication, 45/5 is 9 and 2 x 4 is 8, so 9+8=17.

It’s not B, because first solve the numbers in the parentheses. 2^2 is 4, 5+4 is 9. Then solve the square root of 4 which is 2, and you get 45/9x2, which is 10.

It’s not C because 2^2 is 4 and sq rt of 4 is 2, and 4-2 is 2. Then divide 45 by 5 to get 9, and 9+2 is 11.

The correct answer is D, because when you solve 2^2 which gives you 4 and add that to 5, you get 9. The sq rt of 4 is 2, so you get 45/9-2, which is 3.

Hope this helps!

Answer:

the two integers are 20 and 60

Step-by-step explanation:

Let x and y be two positive numbers ,where x < y.

• The difference between the two positive numbers x and y is 40.

 Means

y - x = 40

• the ratio of these integers is 1:3

 Means

y = 3x

We obtain these two equations:

y - x = 40

y = 3x

Solving the system of equations by substitution :

y - x = 40

y = 3x

⇔

3x - x = 40

y = 3x

⇔

2x = 40

y = 3x

⇔

x = 20

y = 3 × 20 = 60

Answer:

x is less than or equal to 1.5

(less than sign with a bar below it)

Q6. -5/2

Q7. -7/24

Q8.  127/24

Q9. 151/12

Step-by-step explanation:

Q6. (−3/4)+(−7/4) = -3-7/4 = -10/4 = -5/2

Q7. 3/8 - 2/3 = 3*3/8*3 - 2*8/3*8 = 9/24 - 16/24 = 9-16/24 = -7/24

Q8. 18+2/3 - 8+3/8 = 20/3 - 11/8 = 20*8/3*8 - 11*3/8*3 = 160-33/24 = 127/24

Q9. 12+1/4 + 27+1/3 = 13/4 + 28/3 = 13*3/12 + 28*4/12 = 39 + 112/12 = 151/12

Step-by-step explanation:

The perimeter of the rectangle is given as:

The perimeter of a rectangle is:

So, we have:

Substitute values for length and width

Split

or

or

Divide both sides by 2

or

Solve for x

or

or

Both values of x are negative.

This means that; the absolute value model cannot work, because a rectangle cannot have a negative dimension.

Hence, option (c) is correct.
