21.9 is the answer so I hope you get it right
Answer:
169.4 square units.
Step-by-step explanation:
7*4 = 28
28*3 = 84
B*H/2 is the formula for an equilateral triangle.
7*6.1 = 42.7*2 = 85.4
84+85.4 = 169.4
The surface area of your equilateral triangular prism is 169.4 square units.
Answer:
5
Step-by-step explanation:
by pythagoras theorem
(hyp)^2=(leg1)^2+(leg2)^2
the hypotenuse is the side opposite to 90 degree (BC=13)
AC=leg 1 = 12
13^2=12^2 + leg 2^2
169=144+ leg 2^2
leg2 ^2=169-144
leg2^2= 25
leg2= root 25
leg2=5
Step-by-step explanation:
To figure out your x-intercepts and y-intercepts you have to redo the equation and make it equal to zero.
Step 1: 8x + 9y - 72 = 0
Step 2: 8x + 9y = 72
Now you can figure out your intercepts! As long as you use the STANDARD FORM EQUATION which is Ax + By = C
Y-INTERCEPT (vertical line): (
, 0 )
X-INTERCEPT (horizontal line): ( 0 ,
)
Insert your numbers how it shows in the standard form equation and you should get something like this:
Y-INTERCEPT: (
, 0 )
<em>Simplified Y-INTERCEPT: </em>( 8 , 0 )
X-INTERCEPT: ( 0 ,
)
<em>Simplified X-INTERCEPT: </em><em> ( 0 , 9 )</em>

Insert that into your graph and you should be able to get your answer.
