Factor<br> 3x^2+5x-8<br> Use step by step explaining how you got that answer
8_murik_8 [283]

Answer: (x-1)(3x+8)

Step-by-step explanation:

Slide and divide method

See what multiplies to get -24 (because of 3 and -8) and what adds to get 5

Put those into factoring form (x-3)(x+8) without a number in front of the x’s

Divide the numbers by what isn’t in front of the x’s (-3/3 and 8/3)

Simplify them and if it doesn’t divide perfectly, put the denominator in front of the x

Solution

**I can’t explain it well but watch a video on the method AND ONLY DO IT IF IT WORKS WELL FOR YOU**

Dan has a conical lamp shade with an altitude of 6 inches and a diameter
Luda [366]

Answer:

226.22 in^2

Step-by-step explanation:

Given data

Height l= 6in

Diameter= 12in

Radius= 12/2= 6in

The expression for the total surface area of a cone is given as

TSA= πrl+πr^2

substitute

TSA= 3.142*6*6+3.142*6^2

TSA= 113.112+113.112

TSA= 226.22 in^2

Hence the TSA is 226.22 in^2
