Answer: 4.5
Step-by-step explanation:
do the numbers that are in parentheses first which is 2+6=8 next is 5+3=8 then add both ur answers together then divide that by 4 which should equal 4.5
Answer: squares
Step-by-step explanation:
Squares
We can split it up into a net
actually, here is a hack
notice that indented side?
we can take the plane and push it so it makes 4 sides, neat
ok, so we now just have 4 normal sides and 2 L shapes
L shape can be cut into 2 rectangles
5 by 5 and 5 by 10 so total of 75 is the L
2 L's so
2*75=150
the sides
4 of them
they all are 10 by 3
10*3*4=120
toatl is 150+120=270
answer is A
Answer:
x = ±√37/9
Step-by-step explanation:
x² = 37/81
√(x²) = √(37/81)
x = ± √(37)/√(81)
x = ± √37/9
Answer: second option
Step-by-step explanation:
The standard form of a quadratic equation is:
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
Then, to write the quadratic equation given in the problem in standard form, you must substract 1 from both sides of the equation. Then you have:
![2x^2+5x-1=0](https://tex.z-dn.net/?f=2x%5E2%2B5x-1%3D0)
Given the quadratic equation above, to find the value of
you must substitute:
a=2; b=5 and c=-1 into
Thenrefore, you obtain the following result:
![5^2-4(2)(-1)=33](https://tex.z-dn.net/?f=5%5E2-4%282%29%28-1%29%3D33)
