-5x(-7x^3)
Because -7x^3 is in parentheses, you add the degrees together:
35x^4
Answer:(t-4)(4mn-1)
Step-by-step explanation:
Answer:
The ratio between the radii of circles A and B is equal to
and this ratio represent the scale factor
Step-by-step explanation:
Let
x -----> the radius of circle A
y -----> the radius of circle B
z -----> the ratio between the radii of circles A and B
so

we know that
----> radius of circle A
----> radius of circle B
Find the ratio z

The ratio represent the scale factor of the dilation of radius of circle B to obtain the radius of circle A
Circles A and B are similar, because A translation, followed by a dilation will map one circle onto the other

Step-by-step explanation:
Answer:
x=10 and x=-9
Step-by-step explanation:
Factor:
(x-10)(x+9)=0
x-10=0
x=10
and
x+9=0
x=-9
