Answer:
21 sq ft
Step-by-step explanation:
The formula is 0.5bh; b is the length of the base (6) and h is the height (7). So if you plug in those values, you have 0.5(6)(7). Multiply those and you get 21!
Y=2x-3 is slope intercept form
Answer:
170 m³
Step-by-step explanation:
To solve this type of problem, assume you have two solids joined together to make the shape you have up there. This will enable you find the volume of each, then sum both volume together to get your answer.
Let's solve for the volume as follows.
If we divide the solid into 2, what we have is 2 cuboid: the first having dimensions of:
length (l) = 6m,
width (w) = 2m,
height (h) = 8m
Volume of the first cuboid = 
The second cuboid:
length (l) = 7m,
width (w) = 6m,
height (h) = 2m
Volume of the first cuboid = 
Volume of the figure = 86 + 84 = 170 m³
X+4=2x-19, that's the equation
Answer:
B
Step-by-step explanation:
Substitute the value of (2,1) into the equations, and you find that only B works.
