Question 5

Subtract.
-(20s + 4t)- (-13t - 2s)
A)35st
B)22s + 17t
C)33s + 2
D)18s - 9t

Accepted Answer

When subtracting a negative, we change the subtraction to addition and change the sign of the second term. Thus, the expression becomes 20s + 4t + 13t + 2s which simplifies to 22s + 17t. Therefore, the best choice is B. To subtract the expression (20s + 4t)- (-13t - 2s), we need to distribute the negative sign to every term inside the parentheses:
20s + 4t + 13t + 2s

Now we can combine like terms:
22s + 17t

Therefore, the answer is choice letter B.

Question 8

Subtract.
-(19x + 6xy - 13y)- (8x - 23xy - 16y)
A)11x + 29xy + 3y
B)13x - 11xy + 29
C)11x - 29xy - 29y
D)43xy

Accepted Answer

To subtract, distribute the negative sign to every term inside the second set of parentheses, and then combine like terms.

(19x + 6xy - 13y)- (8x - 23xy - 16y) 
= 19x + 6xy - 13y - 8x + 23xy + 16y 
= 11x + 29xy + 3y

Therefore, the answer is choice A. To subtract, we distribute the negative sign to every term in the second equation. So, we get 19x + 6xy - 13y - 8x + 23xy + 16y. Combining like terms, we get 11x + 29xy + 3y. Therefore, the answer is A.

Question 13

Subtract.
-
A)- 
B) 
C) 
D)

Accepted Answer

To subtract, we need to borrow from the third group of digits. Therefore, the third digit from the right needs to be decreased by 1, which gives us ece = eaef. All other digits in this group remain the same. The answer is 11ebbb8f_b97a_eaef_bcf2_c995bfdad6be_TB8306_11.

Question 14

Multiply.
-(x + 8)(-5x - 7)
A) 
B) 
C) 
D)

Accepted Answer

Use FOIL method:
(x)(-5x) + (x)(-7) + (8)(-5x) + (8)(-7) 
-5x^2 - 7x - 40x - 56 
-5x^2 - 47x - 56 
The correct answer is B: 11ebbb8f_b97c_71d1_bcf2_63586fe9df6a_TB8306_11. We can use the FOIL method to multiply the two binomials:
(x + 8)(-5x - 7) = x(-5x) + x(-7) + 8(-5x) + 8(-7)
= -5x^2 - 7x - 40x - 56
= -5x^2 - 47x - 56
Therefore, the answer is option B.

Question 15

Multiply.
-
A) 
B) 
C) 
D)

Accepted Answer

To multiply, we need to add the exponents of the same base. In this case, the base is 16 since it is in hexadecimal. The exponent of b is 1 in the first term and 9 in the second term, so we add them to get 10. Therefore, the answer is 11ebbb8f_b97b_8749_bcf2_57abbf8e0f06_TB8306_11.

Question 17

Multiply.
-6(-8x - 3)
A)-48x - 3
B)-48x - 18
C)-66x
D)-8x - 18

Accepted Answer

When using the distributive property, we multiply 6 by -8x and by -3:
6(-8x - 3) = (-48x) - 18
Therefore the correct answer is B, -48x -18. When multiplying 6 with the expression inside the parentheses, we get -48x - 18.

Question 18

Multiply.
-(x + 2)(3x - 3)
A) 
B) 
C) 
D)

Accepted Answer

Using the distributive property and combining like terms, we get:

(x + 2)(3x - 3) = 3x^2 - 3x + 6x - 6
= 3x^2 + 3x - 6
= 3(x^2 + x - 2)

Therefore, the answer is C, 3(x^2 + x - 2). Using the distributive property, we can distribute both terms of the first polynomial to the second polynomial and then combine like terms:

(x + 2)(3x - 3) = 3x^2 - 3x + 6x - 6 = 3x^2 + 3x - 6.

Thus, the correct choice is C.

Question 20

Subtract.
-
A) 
B) 
C) 
D)

Accepted Answer

When subtracting, you need to borrow from the next digit if the digit being subtracted from is less than the digit you are subtracting. In this case, we need to borrow from the 4 in the third group of digits. This becomes a 3 in the third group of digits and adds 16 to the second group of digits. The correct answer is therefore A. To subtract, we need to borrow from the leftmost digit.

So, the digit at position 3 changes from 1 to 0, and we borrow 16 from the digit at position 2.

Now, the digit at position 2 changes from b to a, and we subtract 1 from the digit at position 3.

Next, the digit at position 4 changes from c to b, and we subtract 1 from the digit at position 5.

Finally, we subtract as usual in the rightmost group of digits.

The result is 11ebbb8f_b97b_391d_bcf2_7fe91d668a9d_TB8306_11.
