i don't understand this at all

visual frigate
#

do simultaneous linear equations

terse sphinx
#

it wasn't taught in any lecture and i'm lost

terse sphinx
visual frigate
#

2x = 18 - x

#

x = 6

#

y = 12

#

A = (6,12)

#

and then find x for which 18-x=0

#

x = 18

#

so you'll get 18*12*0.5

#

as your answer

terse sphinx
#

the answer for b) is (__) square units

#

am i meant to use simultaneous linear equations for the answer of b

visual frigate
terse sphinx
#

Inverse Cupid #GTFOanemia

terse sphinx
#

how do i do this

visual frigate
#

first turn the equation into the general form

#

ax^2 + bx + c = 0

#

then sub in a,b and c in the formula

terse sphinx
#

2, -7 and 14

#

??

visual frigate
#

a is the coefficient of x^2

visual frigate
#

b isn't

#

bruh wait

terse sphinx
#

๐Ÿ˜ญ๐Ÿ˜ญ

visual frigate
#

nope

terse sphinx
#

cryinf

visual frigate
#

b isn't correct

terse sphinx
#

how

visual frigate
#

take 6x to the opposite side

terse sphinx
#

2x^2 - 7x + 14 = 6x

#

?

visual frigate
#

...

terse sphinx
#

it's -7 bruh

visual frigate
#

2x^2 - 13x + 14 = 0

terse sphinx
#

oh damn

#

a = 2

#

b = -13

#

c = 14

visual frigate
#

yes

#

now sub in the values

terse sphinx
#

now what

visual frigate
#

I gave a formula ryt?

#

use that ahhhhh

terse sphinx
#

x = -13 + root -13^2 - 4 * 2 * 14 all divided by 2 * 2

#

?

visual frigate
#

yeah

#

simplify that

#

,w 2x^2 - 13x + 14=0

visual frigate
#

yes
ignore me cheating

terse sphinx
#

this is

#

wrong

#

bruh

#

i got 5.137 or 1.362

#
