5(7a + 4b)
Distributive property !
Step-by-step explanation:
x+3y=-4(eqn1)
x=-4-3y
from (eqn 2)
2(-4-3y)+6y=5
-8-6y+6y=5
y=5+8=13.
y=13
from eqn 1
x+3(13)=-4
x+39=-4
x=-4-39
x=-43.
40 x 26.5 /2 is 530which is b
Diameter = 10.0002 inches, or 10 inches since were rounding to the nearest whole number.
