Greater
If we get common denominators
1/2=15/30
3/15=6/30
15>6 therefore 1/2>3/15

Help what is x^2-2x-24=0

ankoles [38]

$x^2-2x-24=0\\\\a=1;\ b=-2;\ c=-24\\\\\Delta=b^2-4ac\\\\\Delta=(-2)^2-4\cdot1\cdot(-24)=4+96=100\\\\x_1=\frac{-b-\sqrt\Delta}{2a};\ x_2=\frac{-b+\sqrt\Delta}{2a}\\\\x_1=\frac{2-\sqrt{100}}{2\cdot1}=\frac{2-10}{2}=\frac{-8}{2}=-4\\\\x_2=\frac{2+\sqrt{100}}{2\cdot1}=\frac{2+10}{2}=\frac{12}{2}=6$

Part 23. NO LINKS!! What is the area of this figure?

nalin [4]

Answer:

117 in²

Step-by-step explanation:

<u>Here are the steps on how we will solve this problem.</u>

Step 1: Divide the shape into squares and rectangles.
Step 2: Find the area of all squares and rectangles
Step 3: Sum up all the areas to get your final answer.

Now, let's follow the steps. Please consider looking at the picture I uploaded. Looking at the picture, we can tell that the area is 70 + 32 + 15. Now, let's solve.

70 + 32 + 15
=> 102 + 15
=> 117 in²

Hence, the area of the shape is 117 in².

4w2 + 3W

timama [110]

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

$Length = 4w^2 + 3w - 1$

$Width = 5w - 2.$

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

$Area = 20w^3 + 7w^2 - 11w + 2$

Step-by-step explanation:

Given

$Length = 4w^2 + 3w - 1$

$Width = 5w - 2.$

Required

Determine an expression for the area

Area is calculated as:

$Area = Length *Width$

$Area = (4w^2 + 3w - 1) * (5w - 2)$

Expand

$Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2$

Collect like terms

$Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2$

$Area = 20w^3 + 7w^2 - 11w + 2$

0.8(5x+15)=2.6-(x+3)

elena55 [62]

0.8(5x + 15) = 2.6 - x + 3 Use the Distributive Property
4x + 12 = 2.6 - x + 3 Combine like terms (2.6 and 3)
4x + 12 = 5.6 - x Add x to both sides
5x + 12 = 5.6 Subtract 12 from both sides
5x = -6.4 Divide both sides by 5
x = -1.28
