1. The square root is about 1.73
2. The square root is about 1.41
Answer:
g(L) = 175L - L²
Step-by-step explanation:
350 = 2(length + width)
length + width = 175
Let L be the length,
L + width = 175
width = 175 - L
Area = length × width
g(L) = L(175 - L)
g(L) = 175L - L²
This is the concept of geometry, we are required to find the values of angle a,b,c,d;
Given that the triangles are by line intersecting two parallel lines, therefore we can conclude that both triangles are similar;
thus;
angle b=40° ⇒alternate angles
angle b= angle c=40° ⇒base angles of isosceles triangles are equal;
angle d=180-(40+40)=180-80=100°
angle a=360-80=240°
Desmos comes in handy with these problems. Use the "FOIL" method for each of them and then plug them into the calculator of desmos. This will graph each other them. Note the x and y axis'
Example for (A) y= (x-2)(x+3) foil it:
x^2+3x-2x-6
x^2+x-6
plug that in and match to graph.
It’s 36 I looked it up and I did this before have a good day anything else?
