Answers

Answer 1

Answer: 1.16, - 5.16

Working
Take 6 to the other side
x^2+4x = 6
Find the 3rd for the left hand side:
x^2+4x+ (4/2)^2= 6 + (4/2)^2
Factoring the LHS gives
(x+2)^2=10
Finding square roots on both sides:
x+2=square root of 10
x+2= +3.1623 or - 3.1623
x=3.1623-2
=1.16
or
x= -3.1623 - 2
= - 5.16

What is the remainder when 16,055 is divided by 16?

Answers

When dividing 16,055 by 16, the result is 1,003 with a remainder of 15.

To find the remainder when 16,055 is divided by 16, we can use the modulo operation, denoted by the symbol "%".

Step 1: Perform the division:

16,055 ÷ 16 = 1,003.4375

Step 2: Determine the remainder using the modulo operation:

Remainder = 16,055 % 16

Step 3: Calculate the remainder:

Remainder = 15

Therefore, when 16,055 is divided by 16, the remainder is 15. This means that after dividing 16,055 by 16, we are left with a remainder of 15. The modulo operation helps us find the remainder when one number is divided by another.

In summary, when dividing 16,055 by 16, the result is 1,003 with a remainder of 15. This calculation is based on the concept of modulo arithmetic, which allows us to find the remainder when performing integer division.

Which expressions have a value of 33A. 15+(8*3-6)
B. (30+6)/6+3*2^2
C.40-[5*(3+1)+8]
D.[(3+5)*2-5]*3

Answers

let's look through the options one by one:
A. 15+(8*3-6)
inside the parentheses, we multiply first
15+(24-6)
now simplify the rest of the parentheses
15+18
33
so answer "A'' equals 33
B. (30+6)/6+3*2^2
we simplify the inside of the parentheses
36/6+3*2^2
we simplify the exponent
36/6+3*4
6+12
18
So NO, answer "B" is not correct
C. 40-[5*(3+1)+8]
all the way on the inside of the parentheses,
40-[5*4+8]
multiplying comes before adding, so
40-[20+8]
inside the brackets,
40-28
12
So answer "C" is also incorrect
D. [(3+5)*2-5]*3
inside the parentheses
[8*2-5]*3
multiplying before subtracting
[16-5]*3
11*3
33
So the only answers that equal 33 are answer "A" and answer "D" equal 33
