if it asks for scale factor does that mean i’m supposed to write a ratio? Can someone solve and explain these for me i’m so conf
STatiana [176]
Yes scale factor means ratio. The height of the smaller pyramid to the larger pyramid in ratio form is 8:24 which simplifies to 1:3. The ratio of its areas is the scale factor squared, so 1^2:3^2=1:9. Since the surface area of the smaller pyramid is 124, the surface area of the larger pyramid must be 124x9. The ratio of volumes is the scale factor cubed, so 1^3:3^3=1:27. If the volume of the larger pyramid is 648, then the volume of the smaller pyramid is 1/27 of that, which equals 24.

to the equation . Where did the student go wrong? Step 1. Factor the polynomial into (x + 6) and (x - 2)Step 2. x - 6 = 0 and x
zvonat [6]

Answer and explanation:

The wrong step  <u>is changing the sign in step 2</u>

Such that; in step 1 the student had; (x + 6) and (x - 2)

In step 2, the student should have;

x + 6 = 0 and x - 2 = 0 instead of x - 6 = 0 and x + 2 = 0

Step 3, will thus be;

x = -6 and x = 2
