Step-by-step explanation:
To make it easy to read very large and small numbers, we write them in standard form. Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.98 ✕ 10¹³; 0.76 ✕ 10¹³ are examples of numbers in standard form.

Answer:
314 flowers
Step-by-step explanation:
In order to find how long the perimeter of the circular garden is, we need to find the circumference of the garden.
The circumference of a circle is radius*2*pi. So, in this case, the circumference would be 200*2*3.14. This equals 1256 inches.
Next, we know that flowers are planted every 4 inches, so all we need to do is to find how many 4-inch segments are in 1256 inches.
1256/4=314
Thus, 314 flowers are needed.
All you have to do is replace every x with 2 and then solve:
<em>Make to sure to follow the Order of Operations!!</em>
-9x(2) + 11x - 7 =
(-9 × 2 × 2) + (11 × 2) - 7 =
-36 + 22 - 7 =
-14 - 7 =
-21
The answer is -21.
Hope that helps!
