Answer:
326m²
Step-by-step explanation:
Find the area of each side and find the total sum from each individual area:
2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326
So the surface area of the prism is 326m²
Since we have two possible pieces of information and 2 items to solve for, we know this is a system of equations.
Our first piece of information is that our shorter leg (s) is 2 feet shorter than our longer leg (l). This can be written as s=l-2.
Our second piece of information is that using the Pythagorean theorem that our shorter leg squared plus our longer leg squared is equal to our hypotenuse squared. This can be represented by s^2+l^2=10^2. Now we can solve.
We have already isolated for s in our first equation, so we can substitute l-2 in.
(l-2)^2+l^2=10^2
l-2+l=10
2l-2=10
2l=12
l=6
Now we can substitute in for s in our simpler equation
s=6-2
s=4
We now know that using our knowledge of systems of equations, the side lengths of this right angle triangle are 6 and 4.
Answer:
i believe the first one should be 20 5 since its supposed to be in expanded form but i dont know the second one sorry hope you do good
Step-by-step explanation:
Answer:
-9-(-3)/0-(-3) = -3/3 = -1
y+9= -1(x-0) <u><em>Point Slope form</em></u>
y+9<u>-9</u>= -1x<u>-9</u>
y= -x-9 <em><u>Slope Intercept form</u></em>
y<u>+x+9</u> = -x-9 <u>+x+9</u>
y+x+9= 0 <u><em>General form</em></u>
X would be -37. since youll subtract the 19 from both sides to get x=-37
