Answer:
D. 10 square units
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
__
This triangle has a base of 4 units and a height of 5 units. (These dimensions can be counted from the graph, or found by subtracting coordinate values.) Its area is ...
A = 1/2(4 units)(5 units) = 10 square units
_____
<em>Additional comment</em>
The first two coordinates lie on the line x=0. The length of that segment is the difference of the y-values: 4 -(-1) = 5.
The first and last coordinates lie on the line y=-1. The length of that segment is the difference of the x-values: 4 -0 = 4.
If we were to imagine a single point (1,1) which is in quadrant 1, and we rotate it 90o then we get a negative x. Another 90o then both x and y is negative. another 90 (270) and we get a negative y.
thus:
(e)(f)(g)(h) = (-1,-1)(-1,-2)(-2,-1)(-2,-2)
Answer:
x=13
Step-by-step explanation:
2x=26
x=26/2
x=13
..........
( / = divided by)
volume / base = height
so its
V=18
and
B=4 1/2 or 4.5
so your math= 18 / 4.5=4
and your answer= H=4
Answer: 5/10 or 1/2
Step-by-step explanation:
To find how much longer, subtract to get the difference:
9/10 - 4/10 = 5/10
5/10 simplified is 1/2
