Answer:
I think the right answer would be 7
Step-by-step explanation:
We got-ta use the equation: CA * BA = DA²
CA = 15 + BA
DA² = 8² = 64
=> (15 + BA) BA = 64
Subtract 15 from each side:
BA(BA) = 49
BA² = 49
Now take the square root of each side
BA = 7

Question 18
a, grocery store
b. -1,2
c. 0,4
d. 4th quadrant
Answer:
2 and 3
Step-by-step explanation:
2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
side ratio: 1/4------- area ratio: 1²/4² = 1/16 = 1:16 ratio
3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.
The ratio of the perimeters is the same as the scale factor.
scale 1:4
(4/5) / (4/9) = 4/5 * 9/4 = 36/20 = 9/5 = 1 4/5 miles per hour
so B.) one and four-fifths mph
