For the scale factor, use the dimensions from similar sides:
Using 18 from the original image you would use 6 from the scaled image.
18 /6 = 3
This means the scaled image is 3 times smaller than the original. Because the scaled image is smaller divide 1 by the scale factor to get 1/3.
Q2:
The scale factor is 1 inch = 12 miles.
Multiply the total inches by 12:
6.5 x 12 = 78 miles.
Answer:
560 cubic inches
Step-by-step explanation:
Substitute:
V = lwh
V = 4(10)(14)
V = 40(14)
V = 560 in^3
<span>f(x) = x² + 4x
so
</span><span>f(-2) = (-2)² + 4(-2)
f(-2) = 4 - 8
f(-2) = -4
answer
-4</span>
I cant see the question 1 sorry:(
2. x=71(base angle, isos. triangle)
3. x=45 (same reason as the above)
4. the third one
