Check the picture below
the triangles are similar, the angles are congruents then
so... just add them up, and divide by 2, or set them as rational
Step-by-step explanation:
Substitute variables with given values
Minus sign becomes plus sign if a negative is multiplied by a negative or a negative is put next to a negative number.
4x-7y=4(-5.2)-7(-6.8)

86% bc 50 is easy to work with, you know 43 arent red, and since 43x2=86 its 86, multiply by 2 bc 50 is half of 100
Step-by-step explanation:
y2+4y+1=0. where, y=-2
(-2)2+4(-2)+1
-4-8+1=0
-12+1=0
-11=0
