Answer:

Step-by-step explanation:

to find the x-intercepts put y=0

x²+6x+8=0

x²+4x+2x+8=0

x(x+4)+2(x+4)=0

(x+4)(x+2)=0

x=-4,-2

so x - intercepts are (-4,0) and (-2,0)

Solve x4 + x2 – 2 = 0.

Anna71 [15]

X = 1/3
4x + 2x - 2 = 0
6x - 2 = 0
+2 +2
6x = 2
/6 /6

X = 1/3

A game room has a floor that is 100 feet by 30 feet. A scale drawing of the floor on grid paper uses a scale of 3 units:5 feet.

Ghella [55]

3 units/ 5 feet = 60 units/ 100 feet
3 units/ 5 feet = 18 units/ 30 feet

The dimensions of the scale drawing are 60 units by 18 units.

Hope this helps!

I suggest you get a second opinion, though
