Area of a trapezoid, A = 1/2 × (a + b) h, where a = 19 cm, b = 23 cm & h = 14 cm.
By substitution, we have
A = 1/2 × (19 + 23)14
= 1/2 × 14(19 + 23)
= 1/2 × 14(42)
= 7(42)
= 294 sq. cm
Answer:
Step-by-step explanation:
The pH of solution a decreases, as the pH of solution B decreases as well.

Answer:
y=(-5/4)x-4
Step-by-step explanation:
y=(-5/4)x+7
(-4,1)=(x,y)
y=mx+b
1=(-5/4)(-4)+b
1=5+b
b=-4
when finding a parallel slope you use the same slope given so y=(-5/4)x-4
