Answer:
L=6 cm l=3
Step-by-step explanation:
x+y=45
L=2l
Big Square Area
L*L=x
Little Square
l*l=y
Substituting
(L*L)+(l*l)=45
(2l*2l)+(l*l)=45
(4l^2)+(l^2)=45
5l^2=45
l^2=45/5
l^2=9
l=sqrt(9)
l=3
L=2(3)
L=6
To figure out the average of Michael and Melissa we must add up all their test scores and divide the by 7; which is the number of tests they took.
Michael:
(80+76+73+70+40+25+10)/7
Melissa:
(88+83+75+70+60+65+62)/7
Michael's average is 53.4
Melissa's average is 71.9
So Melissa is earning a C in Latin.
Answer:
1+1 x 2x2+6x5 = 35
5*7*6*8 = 1680
Step-by-step explanation:
Order of operation
1+1 x 2x2+6x5 = 1 + 2*2 + 30 = 1 + 4 + 30 do the multiplication first from left to right
then
1 + 4 + 30 = 5 + 30
5+30 = 35 after doing addition
so
1+1 x 2x2+6x5 = 35
5*7*6*8 = 35*48 = 1680
5*7*6*8 = 1680
No. That's only true if x is less than ' 1 ', including anything negative. If x is more than +1, then the square is LESS than the cube.
Answer:
Step-by-step explanation:
It seems J is the intersection of diagonals.
We know diagonals of the parallelogram bisect each other.
<u>It gives us:</u>
<u>Substitute and solve for x:</u>
- 6x + 3 = 10x - 5
- 10x - 6x = 3 + 5
- 4x = 8
- x = 2
