10 plus 5x = 50(x=8)
62 times 2x = 128(x=31)
651 - 376 ≈650 - 380 ≈ 270

Step-by-step explanation:
SQUARE ROOT OF 4 = 2.64
2.64 ²=6.96
Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
X= 9 x=2
-2 × -9=18
-2 + -9= -11
