Answer:
40
Step-by-step explanation:
6- 2 = 4 / 4*4*4 = 32
-9+5=4/4*2=8
32 + 8 = 40

90-27=63
Answer:
m ∈ R
Step-by-step explanation:
- 1,84 - 2,3m = - 2,3(m + 0,8)
- 1,84 - 2,3m = - 2,3m - 1,84
m ∈ R
Answer:
BD = 28
AC = 24
Step-by-step explanation:
Diagonals of a parallelogram bisect each other.
4x − 2 = 3y − 1
3x = 3y − 3
Using elimination to solve the system of equations, subtract the second equation from the first.
(4x − 2) − 3x = (3y − 1) − (3y − 3)
4x − 2 − 3x = 3y − 1 − 3y + 3
x − 2 = 2
x = 4
Substitute into either equation to find y.
3(4) = 3y − 3
12 = 3y − 3
15 = 3y
y = 5
The length of BD is:
4(4) − 2 + 3(5) − 1 = 28
The length of AC is:
3(4) + 3(5) − 3 = 24
Answer:
The height of triangle EFG is 9 units
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the area of a square ABCD
The area of a square is equal to
where
b is the length side of the square
we have
substitute
step 2
Find the height of triangle EFG
The area of triangle EFG is equal to
where
b is the base of triangle
h is the height of triangle
we have
---> area of triangle EFG is the same that the area of square ABCD
substitute the given values in the formula
solve for h
therefore
The height of triangle EFG is 9 units
