The answer is 43 degrees.

Explanation:

Because that corner of the quadrilateral is equivalent to 90 degrees, the other angle would need to equal 90 when added together with 43.

To find the answer, you simply subtract 47 from 90, and you have found the answer, which, in this case, is 43 degrees.

Hope this helped! Have a good day.

Factor 9y2 - 12y + 4.<br><br> (3 y - 2)(3 y + 2)<br> (3 y - 4)( y + 1)<br> (3 y - 2) 2
lozanna [386]

Answer:

(y - 2)²

Step-by-step explanation:

9y² - 12y + 4 ← is a perfect square of the form

(ax - b)² = a²x² - 2abx + b²

Compare like terms with 9y² - 12y + 4, thus

a² = 9 ⇒ a = 3

b² = 4 ⇒ b = 2 and

- 2ab = - 2 × 3 × 2 = - 12

Thus

9y² - 12y + 4 = (3y - 2)²

2x + 3 &gt; 13<br> x= 0<br> is this true?<br> O True<br> O False
omeli [17]

False.

Replace x with 0 and solve:

2(0) + 3 = 0+ 3 = 3

3 is not greater than 13 so the answer is false.

Luis is packing his bags for his vacation he has 9 unique toy animals but only 5 fit in his bag how many different groups of 5 t
Eva8 [605]

Answer:

126 groups

Step-by-step explanation:

we know that

This is a combination problem, because the order doesn't matter.  He has 9 toys and wants to know the number of different combinations of 5 he can take.

The formula for the number of possible combinations of r objects from a set of n objects is given by

^nC_r=\frac{ {n!}}{r!(n-r)!}

In this problem we have

n=9, r=5

substitute

^9C_5=\frac{ {9!}}{5!(9-5)!}

^9C_5=\frac{ {9!}}{5!(4)!}

^9C_5=\frac{ {(9)(8)(7)(6)5!}}{5!(4)!}

^9C_5=\frac{ {9)(8)(7)(6)}}{(4*3*2*1)}

^9C_5=126
