Answer:
4200 the answer is d. kilo is 1000
Answer:
Step-by-step explanation:
1). x² - 10x + a²
By using the formula of (a - b)² = a² - 2ab + b²
x² - 2(5)x + a²
Therefore, for a perfect square of the expression a should be equal to 5.
Therefore, (x² - 10x + 25) will be the answer.
2). x² + 2ax + 36
= x² + 2(a)x + 6²
For a perfect square of the given expression value of a should be 6.
x² + 2(a)x + 6² = x² + 2(6)x + 6²
= (x + 6)²
Therefore, x² + 12x + 36 will be the answer.
3).
To make this expression a perfect square,
a² =
=
Therefore, the missing number will be .
Answer:16.56 cm
Step-by-step explanation:
5.8*1.2=6.96
6.4*.8=5.12
1.2+.8=2
5.6-2-3.6
5.6*.8=4.48
4.48+5.12+6.96=16.56
0.8 is greater than 0.08. Hope this is helpful!
