Answer:
The value of s is "90". A further explanation is given below.
Step-by-step explanation:
The given expression is:
⇒ 10=s÷2+7
i.e,
⇒ ![10=\frac{s}{2+7}](https://tex.z-dn.net/?f=10%3D%5Cfrac%7Bs%7D%7B2%2B7%7D)
On solving the above expression, we get
⇒ ![10=\frac{s}{9}](https://tex.z-dn.net/?f=10%3D%5Cfrac%7Bs%7D%7B9%7D)
On applying cross-multiplication, we get
⇒ ![10\times 9=s](https://tex.z-dn.net/?f=10%5Ctimes%209%3Ds)
⇒ ![90 = s](https://tex.z-dn.net/?f=90%20%3D%20s)
Answer:
See below
Step-by-step explanation:
Part A:
area of parallelogram = base * height
A = 9 ft * 8/9 ft = 8 ft^2
Part B:
Connect point D to point B with a segment. Now you have 2 triangles.
The area of each triangle is base * height/2
area of triangle = bh/2 = (9 ft)(8/9 ft)/2 = 4 ft^2
Answer:
(x+5) metres
Step-by-step explanation:
correct question
<em>The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?</em>
<em></em>
Area of the rectangle = Length * width
Factorize the area
A(x) = x^2+8x+15
A(x) = x^2+3x+5x+15
A(x) = x(x+3) + 5(x+3)
A(x) = (x+3)(x+5)
Since the width is x+3, the length of the rectangle will be (x+5) metres
Idk i think you multiply 45 x 11 but im not smart and im pretty sure i havent learned this yet so dont trust me lol
