The formula for the area of a triangle is base*height/2. So lets input the number.
15*40=600/2=300 cm2

<h2>The expression is not factorable with rational numbers.</h2>
Answer:
angle PHI
Step-by-step explanation:
Using the alternate interior angle theorem, we can figure out that PHI is congruent to PKJ
Answer: y = -4x-9
Step-by-step explanation:
parallel slope means it's the same slope as the given equation
y+1=-4(x+2)
y+1 = -4x-8
y = -4x-9
