Check all the apply. x^2-6x+40=6x+5 a. -6 b. -5 c. 6 d. 5 e. 7

D. 5

E. 7

Step-by-step explanation:

X^2-6x+40=6x+5

Bring all the terms to one side

Subtract 6x from each side

X^2-6x-6x+40=6x-6x+5

x^2 -12x+40 = 5

Subtract 5 from each side

x^2 -12x+40-5 = 5-5

x^2 -12x+35 =0

Factor

(x-5) (x-7)=0

Using the zero product property

x-5=0   x-7=0

x=5  x=7

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
