2 * 5 would give you 10
and
-30 + 4 would give you -26 :)
Answer:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :

And replacing into equation (1) we got:



Adding 14 in both sides we got:

And dividing 10 on both sides we got:

And then we can solve for X and we got:

Step-by-step explanation:
For this case we can set up the following notation:
X represent the lenght
Y represent the width
And since we have a rectangular playing filed the perimeter is given by:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :

And replacing into equation (1) we got:

Answer:
Lateral surface area formula: AL=(a+b+c)h
Step-by-step explanation:
"Finds the total area contained by the three rectangular sides of the prism. You can think of the lateral surface area as the total surface area of the prism minus the two triangular areas at the top and bottom of the prism."
Ok, so you can just ignore that 8.7 ft (height of triangle shape). It's not important for finding the lateral surface area.
a, b, c are the base sides. You add the sides of a triangle.
Multiply (a+b+c) with the height, h.
(10 + 10 + 10) x 17 = ?
[this formula can apply for ANY triangular prism no matter which position it's shown]
ANSWER: 510 ft^2
680x+10y=1000. Ax+By=C not sure if that’s what your teacher is looking for
