Answer:
(-2,-1) is where u start
Step-by-step explanation:
A * 4 = E........A = E / 4
B / 4 = E........B = 4E
C + 4 = E......C = E - 4
D - 4 = E.......D = E + 4
A + B + C + D = 100
(E/4) + (4E) + (E - 4) + (E + 4) = 100
E/4 + 6E = 100 ....multiply by 4
E + 24E = 400
25E = 400
E = 400/25
E = 16 <===
Area of a triangle: A= 1/2(base)(hieght)
base=x
height= 6(base)+1= 6x+1
13= 1/2 × (x)(6x+1)
(get rid of 1/2 by multiplying each side by 2)
26= (x)(6x+1)
26= (x × 6x)= 6x² (x × (+1))= x
26= 6x² + x
0= 6x²+x-26
Are either of those the answers? If not, list the options and I will be able to tell you which one is correct. Hope this helped!
The answer is B (-1,3) hope this helped u
