Answer:
x = -25/12 or x = -0.2
Step-by-step explanation:
x(x+5)+6(x+5)=(x+5)
Distribute
x^2 + 5x + 6x + 30 = x + 5
Combine
x^2 + 11x + 30 = x + 5
Subtract 1x from both sides
x^2 + 10x + 30 = 5
Subtract 30 from both sides
12x = -25
Divide 12 on both sides
x = -25/12 or -0.2

Answer:
equation= y-y¹=m(x-x¹)
where m= gradient or slope
slope = <u>y²-y¹</u>
x²-x¹
= -<u>5-7</u>
-2-4
<u>-</u><u>1</u><u>2</u>
-6
= 2
equation= y-7=2(x-4)
y-7=2x-8
y= 2x-8+7
y=2x-1
7 because if you multiply 48.6 times 0.15 then you would have 7.29 but you have to round down because there’s no half a button
