Hey can you please make sure i got these two answers correct? Thanks <3

Answers

first one
use pythagorean theorem to find the height as in diagram atachmetn
4^2+h^2=8^2
16+h^2=64
minus 16
h^2=48
sqrt both sides
h=4√3

area=1/2bh
area=1/2(4)4√3
area=8√3
aprox
area=13.8
round
area=14cm^2
but that is only 1 triangle so double it
14*2=28cm^2

same as other, just cut along the black center line and rearanged
28 in^2

Answers

m=slope= gradient
c=y intercept

(x,y)
(2,5)
x=2
y=5 is one solution
and m=-1/2

input

5=-1/2(2)+c
5=-2/2+c
5=-1+c
add 1
6=c

equaton is y=-1/2x+6

I need help with some maths homework what is the answer 3(x-3)=0

Answers

if xy=0
assume that at least x or y=0

3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3

you would have to use distributive property. it would come out to 3x-9=0 then you would add 9 to -9 and 0. It would then be 3x=9. You would then divide 9 and 3x by 3x. You will get x=3.
