A rectangular athletic field is twice as long as it is wide. If the perimeter of the athletic field is240 yards, what are its

Setler79 [48]

Answer:

Width = 40 yards

Length = 80 yards

Step-by-step explanation:

Width = x

Length = 2x

2x + 2(2x) = 240 yd

2x + 4x = 240 yd

6x = 240 yd

x = 40

A cylinder with a radius of 5 feet and height of 2 feet.

nirvana33 [79]

Answer:

B, 70pi ft2

Step-by-step explanation:

The equation to find surface area of a cylinder is 2(pi)(r)(h)+2(pi)(r)^2. So now plug the numbers in.. 2(pi)(5)(2)+2(pi)(5)^2 now, simplify. 20pi+50pi= 70pi ft2.

Evaluate g(p)•h(p) by modeling or by using the distribution property

Nataly [62]

$g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4$

Solution:

Given data:

$g(p)=(p-2)$ and $h(p)=\left(p^{3}+4 p^{2}-2\right)$

To find $g(p) \cdot h(p)$ :

$g(p) \cdot h(p)= (p-2)\cdot \left(p^{3}+4 p^{2}-2\right)$

Distributive property: $a(b+c)=ab + ac$

$= p\left(p^{3}+4 p^{2}-2\right) -2\left(p^{3}+4 p^{2}-2\right)$

$= \left(p^{4}+4 p^{3}-2p\right) +\left(-2p^{3}-8 p^{2}+4\right)$

$= p^{4}+4 p^{3}-2p-2p^{3}-8 p^{2}+4$

Arrange and add/subtract same powers.

$= p^{4}+(4 p^{3}-2p^{3})-8 p^{2}-2p+4$

$= p^{4}+2 p^{3}-8 p^{2}-2p+4$

Hence $g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4$
