GCF of 28d^3, 32d^3, and 20d^4.

4d³

Step-by-step explanation:

the smallest exponent of each term is 3 so we know we will have d³

the prime factorization of 28 is 2²·7

the prime factorization of 32 is 2⁵

the prime factorization of 20 is 2²·5

so the gcf of 28, 32, and 20 is 2² or 4

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
