Answer:
area of a triangle
1/2 base ×height
1/2×15×8.5
=63.75cm ^2
63.75cm^2 / square centimeters
Step-by-step explanation:
The area of a triangle is calculated by multiplying 1/2 times the base, times the height.
A = (1/2)(base)(height)
A = (0.5)(15)(8.5)
A =63.75
50
add 5 to -25 to get -2/5x by itself.
=10x2−8
4(x2−5)+2(3x2+6)
Distribute:
=(4)(x2)+(4)(−5)+(2)(3x2)+(2)(6)
=4x2+−20+6x2+12
Combine Like Terms:
=(4x2+6x2)+(−20+12)
=10x2+−8
