2. find the large area (4.8m x 3.8m or 480cm x 380cm)

6/40 6.0/40.0 because it’s decimal and percentage wiser
Answer:
Step-by-step explanation:
-7x + 12 + (-8x + 48) = 180
-15x + 60 = 180
-15x = 120
x = -8
m<BDC= -7(-8)+ 12 = 56 + 12 = 68
m<CBA = -8(-8)+48 = 64+48 = 112
Si se puede distribuir el exponente de una suma porque si 2+3 elevado al 2 entonces el Raiz seria cuadrada de 19
90. To get to this answer, you would multiply 6 X 10 and 3 X 10. You would then add the products: 60 + 30 = 90.
