Step-by-step explanation:
<h3>Area of rhombus = 1/2 × D1 ×D2</h3>
(D= Diagonal)
<h3> 216= 1 /2 ×24×D2</h3>
<h3> D2 = 216/12 =18 cm3</h3>
Answer: (-2,3)
Step-by-step explanation:
-3x + 4y = 18
6x + 2y= -6 we have to eliminate one of the variables so you will have ot
2(-3x + 4y) = 18(2) multiply the first equation by 2.
-6x + 8y = 36
6x + 2y = -6 now we could eliminate the x terms by adding them and
0 + 10y= 30 remember that is a new equation.
y= 3
Now we know that the y solution is 3 so we will put it into one of the equations and solve for x.
-6x + 8(3)=36
-6x + 24
-24 -24
-6x = 12
x= -2
6.32 units squared
a^2+b^2=c^2
3^2+b^2=7^2
9+ b^2= 49
-9. -9
b^2 =40
b= 2 square root of 10, -2 square root of 10
b=6.32
8 4/8 - 2 2/8 = 6 2/8in or 6.25in
