It's just dividing out the factoring to their simplest form.
The bold numbers are the answers that go in the circles.
1. 16 < 8 and 2
8 < 2 and 4
4 < 2 and 2
2. 42 < 14 and 3
14 < 7 and 2
3. 40 < 2 and 20
20 < 10 and 2
10 < 2 and 5
4. I'm not able to see the rest of the factoring tree
We have to solve this quadratic equation 
for n to get <em>which figure has 56 blocks</em>.
For middle term factorization, we need <em>two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).</em>
<em>Such two numbers are </em><em>8</em><em> and </em><em>-7</em><em>. We can now write,</em>
<em>
</em>
<u><em>"There is no negative figure number possible, so we disregard -8"</em></u>
Our answer is 7.
ANSWER: The 7th figure has 56 blocks.
Answer:
1,000,000,000 as a power of 10, is: 10^12
Step-by-step Solution:
We can expand 1,000,000,000, and write this number as a multiplication sentence using only the number 10. By doing this, we can count the number of tens needed to be multiplied to get to his answer:
1,000,000,000 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10
Since 10 is multiplied by itself 12 times, we can therefore say that 10^12 is equal to 1,000,000,000
Answer:
b = y-intercept
Step-by-step explanation:
Rabbit: y=5x-7
Turtle: y=x
use substitution
x=5x-7
-4x=-7
x=7/4=1.75
