Um.. can you translate that to English..
Answer:
19
Step-by-step explanation:
The opposite sides are equal, so:
PS = 3y+1
RS = 4y+2
QR = 3y+1
PQ = 4y+2
Therefore, we can set the perimeter 90 = PS+RS+QR+PQ
90 = (3y+1) + (4y+2) + (3y+1) + (4y+2), or,
90 = 2(3y+1) + 2(4y+2)
90 = 6y+2 + 8y+4
90 = 14y + 6
84 = 14y
y = 6
Then, we go back to the question. It's asking for the length of PS. PS = 3y+1, so we plug in 6 for y
3(6)+1
18 + 1 = <u>19</u>
To answer this item, we let n be the number of scarves that Rebecca bought because the number is unknown. The total cost would be the sum of the amount paid for n scarves and 2 purses. The equation would then be,
5n + (12)(2) = 39
Simplifying,
5n + 24 = 39
Thus, the answer is letter B.
if the equation is y+=1/2 (x-3) the slope is wrong. the slope is actually 6. that was the error that Sydney made. i hope this help some of my people out:)

now you got this go kill that essay:))))
Answer:
The length is 10 inches and the width is 7 inches.
Step-by-step explanation:
A rectangle is shape with 4 sides where 2 pairs of sides are equal and form 4 perpendicular angles. 1 pair of sides is the width and is distance w. 1 pair of sides id the length and is 3 inches more than the width or 3 + w. The total distance around the shape is the perimeter. We know the perimeter is 34 inches. Add each side together and set it equal to 34. Then solve for w.
P = l + l + w + w
34 = 3 + w + 3 + w + w + w
34 = 6 + 4w
28 = 4w
7 = w
This means its length which is 3 inches longer is 7 + 3 = 10.
