If (s-3)^2=0, what is the value of (s+3) (s+5)?

Answers

Answer 1

Answer:

Here,

(s-3)²=0

→s-3=0

→s=3

Substituting s=3 in,

(s+3)(s+5)

=(3+3)(3+5)

=(6)(8)

=48

Describe the steps you can use to find an average of fractional amounts

Answers

Answer:

Average of number is equal to sum of numbers by total no.

i.e., $Average\,=\,(Sun\,of\,numbers)/(Total\,no)$

Now when numbers/amounts are fraction then there is one extra step which is to add the fractions.

Lets say we have to find average of 2 fractions i.e., $(3)/(4)\,,\,(5)/(3)$

$\implies\,Average\,=\,((3)/(4)+(5)/(3))/(2)$

Step 1 : First to add the fractions find the LCM of denominator as There are unlike fractions

3 = 1 × 3

4 = 1 × 4

LCM of 3 and 4 = 3 × 4 = 12

Step 2: To make them like fraction we find equivalent fraction of each fraction whose denominator equal to 12

$(3)/(4)*(3)/(3)=(9)/(12)$

$(5)/(3)*(4)/(4)=(20)/(12)$

Step 3: Adding both fractions

$(9)/(12)+(20)/(12)=(9+20)/(12)=(29)/(12)$

Step 4: put these value in average formula

$\implies\,Average\,=\,\frac{(29)/(12){2}$

Step 5: Now we divide $(29)/(12)$ by 2 using fraction division .i.e., multiply the reciprocal of divisor with dividend

here 2 is divisor

Reciprocal = $(1)/(2)$

$\imples Average=(29)/(12)*(1)/(2)=(29*1)/(12*2)=(29)/(24)$

Following these steps Average of fractional amount of any no can be found.

1. first make the denominators of the set the same.
E.g. $(2)/(7)+ (4)/(3)$ = $(6)/(21) + (28)/(21)$ = $(34)/(21)$

2. Divide the total by the number of fractions added together: In this case it was 2 so:
$(34)/(21) * (1)/(2)$ = $(34)/(42)$

3. Simplify the total: $(17)/(21)$

the first term in a sequence is an odd number the rule is to multiply by 2 explain why the rest of the terms in the sequence will be even numbers.

Answers

If you do that, then 2 will be a factor of all the terms after the first one.
And any number that has 2 as a factor is an even number.

in april the vega family gets 400 text messages included in their plant.together,tomas and marisol use half of the messages.javier and sergio use 120 messages.carmen uses the rest of the messages.write and evaluate and expression to find the number of messages carmen uses.show your work

Answers

Ok half of 400 is 200 so 400-200=200. And so 200-120=80 and since Carmen used all the messages after that, Carmen used 80 messages.

Answer: carman used 80

Step-by-step explanation:

half of 400 (the amount of texts per month) is 200, so then you subtract 200 - 120 ( the amount of messages javier and sergio used) that equals 80 so the amount of messages carman used was 80
