Answer:
x² + 10x + 25
Explanation:
Before we begin, remember the following:
(a + b)(a + b) = (a + b)² = a² + 2ab + b²
Now, for the given we have:
(x + 5)(x + 5)
We can note that the two brackets are identical.
Therefore, we can apply the above rule as follows:
(x + 5)(x + 5) = (x + 5)²
= (x)² + 2(x)(5) + (5)²
= x² + 10x + 25
Hope this helps :)
Answer:
-54
Step-by-step explanation:
In the fomr
ax+by=c
-a/b=slope
4x-8y=11
a=1
b=-8
slope=-4/-8=4/8=1/2
Answer: 2
