Step-by-step explanation:
DE = 5x-2
DF = 3(x+3)
3(x+3) = 3 + 5x-2
3x+9= 5x+1
2x=8
x=4
DE=5×4-2=18
DE=18
Answer:
0=2- 0
1=8- 8
2=9- 18
3=13- 39
4=8- 32
5=7- 35
6=3- 18
Step-by-step explanation:
you have to multiply each one. Hope this helps!
Answer:
y = 4x² - 44x + 120
Step-by-step explanation:
The formula to solve this will be;
y = c(x - a)(x - b)
Where;
c is the leading coefficient
a and b are the roots
Now, we are given that the roots are 6 and 5, while leading coefficient is 4.
Thus, equation is;
y = 4(x - 5)(x - 6)
Expanding gives;
y = 4(x² - 5x - 6x + 30)
y = 4(x² - 11x + 30)
y = 4x² - 44x + 120
