namely, -5, -4, -3, -2, -1, 0, 1. Excluding "2" because n < 2.
Answer:
cant see picture but it is an easy question based on equilateral that has 3 identical angles and is congruent. A Scalene has odd sides and is not congruent and an isosceles has two sides identical. You can also get two type of right angled triangle only 45 45 plus 90 for right angle would be be congruent
Step-by-step explanation:
All you have to do is substitute the values of x.
h(0) = |-3(0) + 5|
h(0) = |5|
h(0) = 5
The answer for h(0) is 5.
h(5) = |-3(5) +5|
h(5) = |-15 + 5|
h(5) = |-10|
h(5) = 10
The answer to h(5) is 10.
I hope this helps!
Answer:
625 cm^2
Step-by-step explanation:
Break it into a rectangle on the bottom and a triangle on top
rectangle area = 50 x 8 = 400 cm^2
triangle area = 1/2 b * h = 1/2 * 50 * 9 = 225 cm^2
added together = 625 cm^2
