Answer:
2i√5
Step-by-step explanation:
√-20 = √-1 × √20
√-1 = i
√20 = 2√5
i × 2√5 = 2i√5
We will use the SAS (SIDE-ANGLE-SIDE) to prove that two triangles are congruent.
Answer: F
Explanation: you already know you have a 90° and the straight lines means it’s 180° so you need to find x and z which are the same so 2x + 90=180 which you would then subtract 90 from 180 which would be 90 then divide 90 by two which would be 45
Answer:
Step-by-step explanation:
We want to factor the common monomial out of :
The greatest common monomial fact is
We factor to get:
The expression in the parenthesis has no common factor again since we factored the greatest common factor.
To multiply fracti0ons, we need to convert them to improper fractions:
-2 1/4 = -9/4
-4 1/2 = -9/2
Now, lets multiply:
-9/4 * -9/2 = 81/8
Hope this helps!
Take note that the answer is positive because when multiplying, two negatives make a positive.
