The correct answer for this would be ΔCJD ≅ ΔAMY and ΔDCJ ≅ ΔYAM.
All we are doing for this is rearranging the order of the angles, as long as the order of the angles match with the original order.
The following answers are also correct:
ΔDJC ≅ ΔYMA
ΔCDJ ≅ ΔAYM
ΔJDC ≅ ΔMYA

A rectangular city lot has an area of 1000 square meters. If the length of the lot is 10 meters more than twice its width, find

loris [4]

Answer: l=50 m, w=20 m

Step-by-step explanation:

Given

A rectangular city has an area of $1000\ m^2$

Also, length is 10 m more than twice its width

suppose width is w

So, length is given by

$\Rightarrow l=10+2w$

The area is given by

$\Rightarrow A=l\times w\\\Rightarrow 1000=(10+2w)\times w\\\Rightarrow 2w^2+10w-1000=0\\\Rightarrow w^2+5w-500=0\\\Rightarrow w^2+25w-20w-500=0\\\Rightarrow (w+25)(w-20)=0\\\therefore w=20\ m\\l=10+2w=10+2\times 20=50\ m$

Answer:

See below

Step-by-step explanation:

Here are some standard derivatives we will be using:

ƒ(x) ⟶ f'(x)

sin(x) ⟶ cos(x)

cos(x) ⟶ -sin(x)

$e^{ax} \longrightarrow ae^{ax}$

gh ⟶ gh' + hg'

$f(x) = e^{2x}\sin(x)\\f'(x) = e^{2x}\cos(x) + 2e^{2x}\sin(x) \\f''(x)=-e^{2x}\sin(x) + e^{2x}\cos(x)+2e^{2x}\cos(x) + 4e^{2x}\sin(x)$

$f''(x)= 4e^{2x}\cos(x)+ 3e^{2x}\sin(x)$

Solve for w in P = 2w + 2l, if P = 38 and l = 12.

vova2212 [387]

W= 7

38=2w+2(12)
/
38=2w + 24
-24 -24

14=2w
divid by 2 divid by 2

7=w
