Answer:

-22

Step-by-step explanation:

We need to multiply the following:

(\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})

First, we need to FOIL out this expression, then we can simplify it

(\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})\\\\(\sqrt{10})( \sqrt{10} )+(2\sqrt{8})(\sqrt{10})-(2\sqrt{8})( \sqrt{10})-(2\sqrt{8})(2\sqrt{8}) \\\\10+2\sqrt{80} -2\sqrt{80} -4\sqrt{64} \\\\10-4(8)\\\\10-32\\\\-22

Given f(x)=4x^3+7x^2-7x-10 factor f(x), given that -1 is a zero
stira [4]
If - 1 is a zero then
(x + 1)
is a factor.

Dividing with this factor using the long division approach, we get the quadratic factor to be,

4 {x}^{2}  + 3x - 10
(see attachment).

We can rewrite the polynomial as
f(x) = (x  + 1)(4 {x}^{2}  + 3x - 10)

We can further factor as

f(x) = (x + 1)(4 {x}^{2}  - 5x + 8x - 10)
That is

f(x) = (x + 1)(x  +  2)(4x - 5)

Solve #1 pls, I need to find the shortest side, median side, and longest side
Lisa [10]

Answer:

Shortest side = 39 cm.

Median side = 65 cm.

Longest side = 91 cm.

Step-by-step explanation:

The perimeter in total is 195 cm. The ratio of the sides are 3 : 5 : 7.

First, find how much parts there are as a whole, by combining the ratios:

3 + 5 + 7 = 15 parts.

Divide the total of parts from the total measurement:

195/15 = 13

Each part has the measurement of 13 cm.

1 part = 13 cm.

Use the following ratio to solve for each of the sides:

Shortest side: 3

3 x 13 = 39

Shortest side = 39 cm.

Median side: 5

5 x 13 = 65

Median side = 65 cm.

Longest side: 7

7 x 13 = 91

Longest side = 91 cm.

Check. Combine all side measurements together. They should equal 195:

39 + 65 + 91 = 195

(39 + 65) + 91 = 195

(104) + 91 = 195

195 = 195 (True).
