Answer:
<u>The answer is 4√5</u>
Step-by-step explanation:
Simplify 2√5 + 3√5 - √5
We can simplify this operation this way:
√5 (2 + 3 - 1) or (2 + 3 - 1)√5
Now, we resolve the operations inside the parenthesis:
√5 (5 - 1) = √5 (4) = 4√5 or (5 - 1) √5 = (4) √5 = 4√5
<u>So, the result of the simplification of this operation is 4√5.</u>
a possible answer would be 36/9=4
Answer:
x is 5 and B is 66°
Step-by-step explanation:
Since the two lines are parallel then
A + B = 180°
8x + 74 + 2x + 56 = 180
Then x is 5
Since B is 2x + 56.
Then B is 2(5)+56=66°
104*.75=78
78/8=9.75(divide by 8 because 80%/8=10%)
9.75*10=97.5
97.5*.8=78
75% of 104 is 78 which is also 80% of 97.5
Your answer is 97.5
