B = 7
7 x 6 = 42
42 + 6 = 48.
Answer:
add them up
Step-by-step explanation:
Given
Shamariah collects silk roses.
She had 17 silk roses in a vase.
Six friends each gave her 3 more roses
Find out the roses does Shamariah have now.
To proof
As given in the question
She had 17 silk roses in a vase
Six friends each gave her 3 more roses
let the total number of roses shamariah have = x
The equation becomes
x = 17 + 6 × 3
x = 17 + 18
x = 35
Number of roses shamarah have now is 35.
Hence proved
Answer:
(n- 2/3)²
Step-by-step explanation:
- <em>Perfect square trinomial is: </em><em>a²+2ab+b²= (a+b)²</em>
We have:
It can be put as:
Here we consider n = a and -2/3 = b, then
Now we add 4/9 to a given binomial to make it perfect square:
- n² - 2×n×3/2 + 4/9= (n- 2/3)²
So, added 4/9 and got a perfect square (n- 2/3)²
