a + b + c = 180

b + c = 180 -a = 180 -34 . . . . . subtract a from both sides

b + c = 146

The sum of two integers is -1. the product of the integers is -72 find the integers.

Elis [28]

$\left\{\begin{array}{ccc}x+y=-1\\x\ \times\ y=-72\end{array}\right\\\left\{\begin{array}{ccc}x=-y-1\\x\ \times\ y=-72\end{array}\right\\\\sunbstitute:\\\\(-y-1)y=-72\\-y^3-y+72=0\\\\a=-1;\ b=-1;\ c=72\\\Delta=b^2-4ac\to\Delta=(-1)^2-4\cdot(-1)\cdot72=1+288=289\\\\y_1=\frac{-b-\sqrt\Delta}{2a}\to y_1=\frac{1-\sqrt{289}}{2\cdot(-1)}=\frac{1-17}{-2}=\frac{-16}{-2}=8\\\\y_2=\frac{-b+\sqrt\Delta}{2a}\to y_2=\frac{1+\sqrt{289}}{2\cdot(-1)}=\frac{1+17}{-2}=\frac{18}{-2}=-9$

$
if\ y=8\ then\ x=-8-1=-9\\\\if\ y=-9\ then\ x=-(-9)-1=9-1=8\\\\Answer:8\ and\ -9.$

The height of tower a is 802 feet more than tower

igomit [66]

The height of tower A is 1016 feet and tower B is 212 feet.

<u><em>Explanation</em></u>

Suppose , the height of tower B is $h$ feet.

As the height of tower A is 802 feet more than tower B , so the height of tower B will be : $(h+802) feet$

Given that, the two towers have a combined height of 1226 feet.

So, the equation will be...

$h+(h+802)=1226\\ \\ 2h=1226-802\\ \\ 2h=424\\ \\ h= \frac{424}{2}=212$

Thus, the height of tower B is 212 feet and height of tower A is (212+802) feet = 1016 feet.

One cubic foot is equal to 1728.0 cubic inches how many cubic inches are in 5 cubic feet

kow [346]

1 Cubic foot (cu ft) is equal to 1728 cubic inches (cu in). To convert cubic feet to cubic inches, multiply the cubic feet value by 1728. For example, to calculate how many cubic inches is 10 cubic feet of water, multiply 10 by 1728, that makes 17280 cu in is 10 cu ft of water.
