Answer:
Well, we have to remember that we must use PEMDAS, or the order of operations, to solve the expression.
<em>Therefore, we must first either divide or multiply anything that is inside of the parentheses. (In this case divide)</em>
<em>Now solve what remains in the parentheses.</em>
<em>Finally, subtract 4 from 10 and get your answer:</em>
6
Hello!
Answer:⇒⇒⇒=6
Step-by-step explanation:
This question it should be used pemdas.
Hint:
P-parenthesis (12÷3+6)=4+6=10
E-exponents 8²=8*8=64
M-multiply 21*2=42
D-divide 20÷5=4
A-add 5+5=10
S-subtract 30-10=20
First calculate with parenthesis.
Then multiply and divide from <u><em>(left to right).</em></u>
Add and subtract from <em><u>(left to right).</u></em>
Hope this helps!
Thank you for posting your question at here on brainly.
Have a great day!

Answer:
They are similar by the definition of similarity in terms of a dilation
Step-by-step explanation:
The given vertices of triangle ΔABC are;
A(1, 5), B(3, 9), and C(5, 3)
The vertices of triangle ΔDEF are;
D(-3, 3), E(-2, 5), and F(-1, 2)
Therefore, we get;
The length of segment, = √((9 - 5)² + (3 - 1)²) = 2·√5
The length of segment, = √((9 - 3)² + (3 - 5)²) = 2·√10
The length of segment, = √((5 - 3)² + (1 - 5)²) = 2·√5
The length of segment, = √((5 - 3)² + (-2 - (-3))²) = √5
The length of segment, = √((2 - 5)² + (-1 - (-2))²) = √10
The length of segment, = √((2 - 3)² + (-1 - (-3))²) = √5
∴ /
= 2·√5/(√5) = 2
/
= 2·√10/(√10) = 2
/
= 2·√5/(√5) = 2
The ratio of their corresponding sides are equal and therefore;
ΔABC and ΔDEF are similar by the definition of similarity in terms of dilation.
