Answer:

x=-31/2

Step-by-step explanation:

Let's equate the equation to zero

-3(4x+5)-2(-5x+8)=0

-12x-15+10x-16=0

Collect like terms

-12x+10x-15-16=0

-2x-31=0

Add 31 to both sides

-2x=31

Divide both sides by-2

x=-31/2

Find the area of this trapezoid. Include the correct unit in your answer.

NemiM [27]

Answer:

$\displaystyle A _{ \text{trapezoid}} = 70 {m}^{2}$

Step-by-step explanation:

we are given a trapezoid

we want to figure out the area

remember that,

$\displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h$

where a and b represent the parallel lines and h represents the height

we get from the pic that a and b are 5 and 15 respectively and h is 7

so substitute:

$\displaystyle A _{ \text{trapezoid}} = \frac{5 + 15}{2} \times 7$

simplify addition:

$\displaystyle A _{ \text{trapezoid}} = \frac{20}{2} \times 7$

simplify division:

$\displaystyle A _{ \text{trapezoid}} = 10\times 7$

simplify multiplication:

$\displaystyle A _{ \text{trapezoid}} = 70$

since we multiply two same units we of course have to use square unit

hence,

$\displaystyle A _{ \text{trapezoid}} = 70 {m}^{2}$

If one of the short sides of a 45-45-90 triangle equals 5, how long is the hypotenuse?

Alla [95]

Answer:

hypotenuse= 2 $\sqrt{5}$

Step-by-step explanation:

the triangle is equal tow side so it is two side =5 cm

then the hypotenuse by Phitagors theory the triangle hypotenuse =

$\sqrt{5^{2} +5^{2} }$ = 2 $\sqrt{5}$

Rita has the following data:

Lubov Fominskaja [6]

The range is the difference between the largest number and the smallest number. This means you subtract the smallest number from the largest number. If the range is 8, then you can add 8 to the smallest number on the list to get the largest number, m.
Our smallest number is 12, so add 8 to 12.
8 + 12 = 20, so m is 20.
I hope this helps!
