7-4 (d-3)=23
7-4d+12=23 **multiply -4 with (d-3)***
7+12-4d=23
19-4d=23
-4d=23-19
-4d=4
d=4÷-4
d= -1

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.

seropon [69]

Answer: Option B.

Step-by-step explanation:

Given the polynomial:

$16x^2-36x+9$

Observe that $16x^2$ and $9$ are perfect squares. Then, you can rewrite the polynomial in this form:

$(4x)^2-36x+(3)^2$

You can identify that:

$A=4\\B=3$

Then, we can check if $2AB=36$

$2(4x)(3)=36x\\\\24x\neq 36x\\\\2AB\neq36x$

Since $2AB\neq36x$ , the polynomial $16x^2-36x+9$ <em>IS NOT </em>a perfect square trinomial of the form $A^2 - 2AB + B^2$

If Adrianna can read 7 pages in 10 minutes. At this rate, how many page can she read in 25 minutes?

lesya692 [45]

3.5 : 5

7 : 10

14 : 20

17.5 : 25

At that rate, she can read 17.5 pages in 25 minuets.

Divide both 7 and 10 by 2, which gets 3.5 and 5

5 * 5 = 25

5 * 3.5 = 17.5

Therefore, in 25 minuets, she can read 17.5 pages.
