Answer:
What does it say.
I can't see the photo at all !
Step-by-step explanation:
Using proportions, it is found that the scale factor of the transformation is of 1/3.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, during the transformation, each coordinate was divided by 3, hence, applying the proportion, the scale factor of the transformation is of 1/3.

Answer:
30 - 10
Step-by-step explanation:
When you distribute, that means you multiply everything on the outside of the parentheses by everything on the inside.
5 (6-2)
is really
5*6 - 5*2
30 - 10
Answer:
22.18 = x
Step-by-step explanation:
a^2 + (b)^2 = (x/2)^2
a = sqrt(74)
b = 7
x/2 = ?
(74)[^1/2]^2 = 74
b^2 = 7^2 = 49
74 + 49 = (x/2)^2 Substitute into a^2 + b^2 = c^2
123 = (x/2)^2 Combine like terms
(123^0.5) = x/2 Take the square root of both sides.
11.09 = x/2 Multiply both sides by 2
11.09*2 = x
22.18 = x The full length of the base of the triangle is 22.18
