Answer:
Length, l = 10 m, breadth = 8 m
Step-by-step explanation:
Let l be the length and b be the width of the rectangle.
The area of a rectangle is given by :
A = lb
80 = lb ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
36 = 2(l+b)
18 = (l+b) ....(2)
We need to solve equation (1) and (2). On solving we get :
l = 10, b = 8
So, the dimensions of the shop is 10 m and 8 m.
Answer:
<h2>using the identity </h2><h3>(a±b) ² = a² + b² ± 2ab </h3>
1) X² + 1 - 2X
2).x² + 4 - 4x
3) 9 + x² - 6x
4) y² + 16 - 8y
5) 4x² + 1 - 4x
6) 9 + 4y² - 6y
7) 4x² + y²- 8y
8) 1 + 16a² - 8a
9) 9x²+ 4y² - 12xy
10) -x²- 16y² + 8y
11) -x²- 25y + 10xy
Answer:
48 DIFFERENT WAYS
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
Cross multiple:
9x=10x
Move them to one side
0=1x
Divide
0=x
We know that the ration/percentage that brass is made of remains the same no matter what the weight is;
Therefore, 48 ounces are 80% of the trumpet.
48/80= 0.6 ounce per percent of the zinc (I divided the weight by the percent)
0.6 ounces × 20%= 12 ounces
Therefore, there are 12 ouches of zinc in Henri's trumpet.
Hope I helped :)
