the third answer, .8=.80
Step-by-step explanation:
Answer:
35 units²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = 14 and h = 5, thus
A =
× 14 × 5 = 7 × 5 = 35 units²
Answer:
3/5
Step-by-step explanation:
2/3 * 9/10 = (2 * 9)/(3 * 10) = 18/30 = (6 * 3)/(6 * 5) =
= 6/6 * 3/5 = 1 * 3/5 = 3/5
Answer:
y=2x+11
Step-by-step explanation:
You first have to distribute the 2 to (x+7) to get y+3=2x+14. after that all you have to do is subtract both sides of the equation by 3 to get y=2x+11
