Question 19

Solve for x in |x+2|=5

|x+2|=5
±(x+2) = 5
x = ±3
x = +3 or -3

Mrshape:







Question 18
What is the sum of the the next 5 multiples of 2

4+8+16+32+64 = 124

Mrshape:
Lol. Calm down.

I stated the base. So we already know where the base the answer should be

lol.. The unit is in the question already.

Mrshape:


Correct
#20 fall on your wallet

thanks

Mrshape:



Question 17 is still open

one zero

Mrshape:





Question 17
Write in words the answer to 1 +1 in binary

one zero

Mrshape:





Question 17
Write in words the answer to 1 +1 in binary

ten

Mrshape:
Wrong

I didn't read the question very well.

Mrshape:


Question 16

Make u subject formula in

1/v +1/u =1/f

In its simplest for show workings

1/u = 1/f - 1/v
1/u = (v-f)/fv
u = fv/(v-f)

Mrshape:


Question 16

Make u subject formula in

1/v +1/u =1/f

In its simplest for show workings

1/f = (u+v)/vu
f = vu/(u+v)

Mrshape:
Correct

Not correct.

I will have to answer it.

A trapezium has zero or 1 line of symmetry.

I taught you wrote 0 I didn't know it is g

you're right

Mrshape:

Question 15.
How many line(s) of symmetry does a trapezium have?

isosceles trapezium has 1 line of symmetry

Mrshape:
The solution will take up to a page of note book.
I have posted that question on nairaland for more than 3months no solution yet.

put 10k on it and give me a week. I will solve it. 100% certain

Mrshape:

Question 15.
How many line(s) of symmetry does a trapezium have?

zero

Mrshape:







Question 15

26°

Mrshape:
I don't understand please.

It is first to comment the right answer that has the prize for that question

let's continue please

Or we should do calculus.. Lol

DarmosRaimos:
Mr Shape are there are many topics in in primary and junior secondarymathematics now. All you have been giving us all this time is LCM and business mathematics. Where Is fractions,simple linear equations,basic geometry,reciprocals etal. It seems to me that you are making it boring and interesting. Thank you

lol.. I will suggest word problems that will involve critical thinking

Mrshape:
Hmmmmm
I think I should advertise this thread in one of my facebook groups.
This guy can't be getting everything now

lol.

Question 14

If the amount is of an interest computed for2 years of a principal of #200
is #500 what is the simple interest

simple interest =amount minus principal = 500 - 200 = N300

Mrshape:

May we continue now

yes

Mrshape:
[b][







WERE ARE THE MATHEMATICIANS HERE DON'T LET THIS GUY GET THE NEXT QUESTION FIRST IT IS GETTING OUT OF HAND

/b]

lol

Volume scale factor = 27/8 = 3³/2³

Therefore the scale factor is 3/2

Hence area factor = 3²/2² = 9/4

Mrshape:
[


Question 13
If the volume scale factor is 27/8 what is the area scale factor

9/4

Mrshape:
Na only you waker come?

lol.. I learnt this from you just 3 days ago. I didn't know it before honestly

Mrshape:
Show workings please

shown

DarmosRaimos:
I did not see his post(I.e. Kareayo

just below your answer

LCM of fraction = LCM of numerators (8 & 6) divided by HCF of denominator (7 & 21) = 24/7

Mrshape:

Always show


show workings

noted boss

Mrshape:








Question 12
What is the Lcm of 8/7 and 6/21

24/7
