Combine like terms and apply the distributive property to create an equivalent expression:

chubhunter [2.5K]

Answer:

Equivalent expression is $15a+8b$

Step-by-step explanation:

Given expression is,

$2\left(5a+3b\right)+5a+2b$

First step is to apply distributive property. The property states that,

$a\left(b+c\right)=ab+ac$

Applying the property,

$2\left(5a\right)+2\left(3b\right)+5a+2b$

Simplifying,

$10a+6b+5a+2b$

Collecting like terms,

$10a+5a+6b+2b$

Combining the like terms,

$15a+8b$

Therefore, equivalent expression is $2\left(5a+3b\right)+5a+2b=15a+8b$

What is the volume of this pyramid? 945 cm³ 1260 cm³ 1890 cm³ 2520 cm³ A pyramid with a right triangular base. The right triangu

notsponge [240]

Answer:

The volume of the pyramid is $1,260\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the triangular base

H is the height of the pyramid

step 1

Find the area of the base B

$B=\frac{1}{2}bh$

we have

$b=14\ cm$

$h=18\ cm$

substitute

$B=\frac{1}{2}(14)(18)=126\ cm^{2}$

step 2

Find the volume

we have

$B=126\ cm^{2}$

$H=30\ cm$

substitute

$V=\frac{1}{3}BH$

$V=\frac{1}{3}(126)(30)=1,260\ cm^{3}$
