Which algebraic expressions are like terms with 16K. Choose all that apply .
a square was altered so that one side is increased by 9 inches and the other side is decreased by 2 inches. the area of the resulting rectangle is 60 square inches. What was the are f the original square.
Answer:
36 square inches.
Step-by-step explanation:
Since the original figure was a square, all four side lengths are equivalent. The area for the square will be:
[tex]A=s^2[/tex]
Where s is the length of one side.
One side is increased by nine inches and the other side was decreased by two inches. The area of the resulting rectangle is 60 square inches.
So, one of the new sides is (s + 9).
And the other is (s - 2).
The area with these dimensions is 60. Thus:
[tex]60=(s-2)(s+9)[/tex]
Solve for s. Distribute:
[tex]60=s^2+7s-18[/tex]
Isolate the variables:
[tex]s^2+7s-78=0[/tex]
Factor:
[tex](s+13)(s-6)=0[/tex]
Zero Product Property:
[tex]s+13=0\text{ or } s-6=0[/tex]
Solve for each case:
[tex]s=-13\text{ or } s=6[/tex]
A side length cannot be negative. So, our only solution is:
[tex]s=6\text{ inches}[/tex]
Since each side of the square measures six inches, the area of the original square will be 36 square inches.

Answer:
Options A, D and E
Step-by-step explanation:
If a number in square root can't be solved Or square root of the number can't be removed then it is a surd.
Option A
√17 = Surd [Can't be simplified further]
Option B
√36 = 6
Not a surd
Option C
√100 = 10
Not a surd
Option D
√15 = Surd
Option E
√30 = Surd
Therefore, Options A, D and E are the surd.

i need to factor 5n^2-16
Answer:
([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)
Step-by-step explanation:
Using the factorising method, difference of 2 squares
a² - b² = (a - b)(a + b) , then
5n² - 16
= ([tex]\sqrt{5}[/tex] n )² - 4²
= ([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)

Step-by-step explanation:
use the law of Cosines so that you can solve a SSS triangle
Cos(C) = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex] / 2ab
c is the side of 24 for our triangle and angle C is the top one in the picture.
C = arcCos ( [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex] / 2ab )
C = arcCos ( -32 / 480 )
C = 93.82255373 °
the angles at the top are each half of that or 46.91127 °
let's solve another angle for the big triangle now let's go for the one on the left and call it A
Cos(A) = [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex] / 2bc where a = 20
A = arcCos( [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex] / 2bc)
A = arcCos( [tex]24^{2}[/tex] + [tex]12^{2}[/tex] - [tex]20^{2}[/tex] / 2*12*24
A = arcCos(320 / 576)
A = 56.2510 °
then angle B is 180 =93.823 + 56.251 + B
29.926 ° = B
so now we know all 3 angles.. seems like a lot of work , huh :D
for the triangle with the question mark we now know two angles and the Hyp, so let's use Law of Sines to find that last side :)
Sin(A)/a = Sin(B) /b where A can be the angle at the top and B can be the angle at the base. which we have to find still :/
it's 180 = 46.9112 + 29.926 + B
103.162 = B
Sin(46.91127 ) / a = Sin(103.162) /20
Sin(46.91127 ) * 20 / Sin(103.162) = a
14.99998 = a I feel confident this is supposed to be 15 and I have a tiny bit of rounding error..
? = 15 there you go
your answer is 15

PLEASE HELP WILL GIVE BRAIN Which could be the function of the following graph?
f(x) = (x + 5)^3(x + 1)^2(x - 2)^2 f(x)=(x+5)3(x+1)2(x−2)2
f(x) = (x + 5)^2(x + 1)(x - 2)^3 f(x)=(x+5)2(x+1)(x−2)3
f(x) = (x + 5)^3(x + 1)^2(x - 2)^2(x - 5) f(x)=(x+5)3(x+1)2(x−2)2(x−5)
