The answer is 6(x^2 -1) I have provided a picture with my work and the answer
<span>y=x^2+5x+6
y=4x+12
Solution = (-3,0) and (2,20)
</span><span>y=x^2-3x-1
y=8x-1
Solution = (0,-1) and (11,87)</span>
Answer:
81.5, 9, 180
Step-by-step explanation:
28.
c=9
9x9=81
a=1/2
81+1/2=81.5
29.
9x1/2=4.5
4.5x2=9
30.
15x15=225
9x5=45
225-45=180
hope this helps!!!
Answer:
(3)79.95 + 59r = 534.85
Step-by-step explanation:
Answer:
If (2,0 )is a solution of a linear equation then the value of x=2 and value of y=0 if we put the value of x and y in the equation then
2x+3y=k
⇒k=2×2+3×0
⇒k=4
Hence the value of k=4
Thank you
