Supplementary angles add to 180
4+5=9
180/9=20
4*20=80
5*20=100
the angles are 80 degrees and 100 degrees
Answer:
13 yds * 32 yds
Step-by-step explanation:
A=area, l=length, w=width
A=w*l
l=6+2w
A=w*(6+2w)
A=6w+2w^2
416=6w+2w^2
416/2=(6w+2w^2)/2
208=3w+w^2
208-208=3w+w^2-208
w^2+3w-208=0
w^2+16w-13w-208=0
w(w+16)-13(w+16)=0
(w-13)(w+16)=0 ==> w+16=0 ==> w=-16, w can't be negative.
w-13=0
<u>w=13</u>
l=6+2w
l=6+2(13)
l=6+26
<u>l=32</u>
Dimensions: 13 * 32
The dimensions of the matrix are 3 by 3 i.e. 3 x 3, and the indicated element a₂₃ is -7
<h3>The dimension of the matrix?</h3>
From the figure in the question, we have the following highlights:
- The matrix has 3 rows
- The matrix has 3 columns
The dimensions of a matrix are represented by: Row by column
Hence, the dimensions of the matrix are 3 by 3
<h3>The indicated element</h3>
This is given as:
a₂₃
This means that the element is located at the second row and the third column.
The element at this position is -7
Hence, the indicated element is -7

Answer:
13
Step-by-step explanation:
You use pemdas to figure this out, so you do whats in the parentheses first, 2x-6, but instead you do 2(4)-6 and when your solving stuff in the parentheses you apply pemdas again to figure out what to do, so you multiply 2x4 first bcz m is before s, and then you do 8-6 bcz there's nothing else to do in the parentheses. now that your done with the parantheses you currently have 3x3 +2(2). now you dont have p or e but you do have m and when you have multiple instances of multiplication you do it left from right, so you do 3x3 first and get 9 and then you do 2x2 and get 4. now you have 9+4 and since you have nothing else to do you add and you get 13.
