Need a photo of the graph to help.
Answer:
=5/21L+ -5/84
Step-by-step explanation:
=-(5/7) (-(1L/3-3/4)+1/3/4)
=(-5/7)(-(1L/3-3/4))+(-5/7)(1/3/4)
=5/21L= -15/28+ -5/84
=5/21L=+ -25/42
A. square root property

it has one value with x which is x^2 and it cn be easily solved without having to factorise, quadratic formula cant be used as it need ax^2+bx+c=0 format
B. factorising

i just felt like this was easier to factorise than the other 2 options left
C. Completing the square

same reason personal preference
D- Quadratic

the 17 kinda threw me off and i didnt wanna get on factorising or doing completing the square so quadratic formal
Answer:
30
Step-by-step explanation:
5*2*3 - 2*0 = 30 - 0 = 30
4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.
Thus, 11x - 18 = 180 degrees.
Combining like terms, 11x = 198, and x = 18.
The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.
