Answer:
14m-n
Step-by-step explanation:
Combine Like Terms:
=8m + −4n + 6m + 3n
=(8m+6m) + (−4n+3n)
=14m+−n
x=1 or x= 12
Step-by-step explanation:
x²-13x+12=0
x²-12x-x+12=0
x(x-12)-1(x-12)=0
(x-1)(x-12)=0
x-1=0 or x-12=0
x=1 or x=12
-3x - 4y = 2
<u>8y</u> = <u>-6x - 4</u>
8 8
y = -0.75x - 0.5
-3x - 4(-0.75x - 0.5) = 2
-3x + 3x + 2 = 2
0x + 2 = 2
<u> - 2 - 2</u>
<u>0x</u> = <u>0</u>
0 0
x = 0
-3(0) - 4y = 2
0 - 4y = 2
<u>- 0 - 0</u>
<u>-4y</u> = <u>2</u>
-4 -4
y = 0.5
(x, y) = (0, 0.5)
The answer is 9, you have to add them together which equals 9.
Answer:
measure of other diagonal is 30cm
Step-by-step explanation:
let the other diagonal be d .
- area of rhombus = 1/2 × 16 × d
- 240 = 8 × d
- d = 240 / 8
- d = 30
hence the other diagonal = d = 30 cm
