To find the area you just find the area of each triangle.
To do this use the formula b×h×.5=A
6×4×.5=A
A=12
Now you just multiply 12 by 4. The reason you multiply by 4 is because you have 4 triangles that make up the rhombus. The area of the rhombus is 48cm²
the rate is 9 because it goes up 9
1-r=-5
add r to both sides so the one side cancels out, then it should be 1=r-5
then you add -5 on each sides (because what you do to one side you must do to the other) and it would then have r on its own side which would give you your answer of r=6. To check 1-6 does equal -5
Answer:
Step-by-step explanation:
7*(7 + x+1) = 6*(x + 5 + 6) {Intersecting secant theorem}
7 *(x + 8) = 6*(x + 11)
Distributive property,
7x + 56 = 6x + 66
Subtract 56 from both sides
7x = 6x + 66 - 56
7x = 6x + 10
Subtract 6x from both sides
7x - 6x = 10
x = 10
