Answer:
25 m by 17.5 m
Step-by-step explanation:
7/2 = 3.5
3.5 * 5 = 15 + 2.5 + 17.5
10/2 = 5
5 * 5 = 25
This seems to be a reflection over the 'y' axis. Notice that the 'x' coordinates of points U and V are x =2 in the original figure, and then, 'x' coordinates of U' and V' are x = -2
All 'y' coordinates for the transformated figure (S'T'U'V'W') are the same that the original figure (STUVW), but the 'x' coordinates are exactly the opposite
This transformation is :
Answer:
d = 3
Step-by-step explanation:
Expand the right side and compare the coefficients of like terms
x² + 6x + c = x² + 2dx + d²
For the 2 sides to be equal then coefficients of like terms must be equal
compare coefficients of x- terms, then
2d = 6 ⇒ d = 3
