Perimeter of square = 4s perimiter of pentagon= 5s, i guess? its a regular one afterall 4s = P 4 (10) = p 40 = P (40 = 5s)/ 5 8 = s
Sorry I dont know how to answer the second one...
Answer:
B. 1,8 and 9⁄5
Step-by-step explanation:
To convert from a decimal to a percentage, move the decimal point twice to the right, then attach the percentage symbol:
1,8 = 180% [Write "0" as the placeholder]
⤻⤻
Then, to convert from a fraction to a decimal, divide both the denominator and numerator:
Also, if you think about it, 18 × 5 is 90, so 1,8 × 5 would be 9. Get it?
All of these prove that they are equivalent 180%.
I am joyous to assist you anytime.
X = 10 + square root of 110. OR...
X = 10 - square root of 110
So
18*6=108
4*6=24
108-24=84
so the answer is 84
i hope it's correct
The factors of the quadratic equation is (x + 1) and (x - 6)
Given,
The quadratic equation; -2x² + 10x + 12
We have to find the factors of this equation using quadratic formula;-
Quadratic formula;-
Here,
a = -2, b = 10 and c = 12
Now,
= = = (-10±14) ÷ -4
Solve for,
- 10 + 14 / -4 = -4/4 = -1
That is, (x + 1)
Solve for,
- 10 - 14 / -4 = -24/-4 = 6
That is, (x - 6)
Therefore, the factors for the given quadratic equation is (x + 1) and (x - 6)
