If b=p+5 and a=p^2+10p+1 find an expression that equals 2b+3a in standard form

olya-2409 [2.1K]

Answer:

3p² + 32p + 13

Step-by-step explanation:

Okay, so lets first solve for 2b. 2b = 2(p + 5), which is equal to 2p + 10. Now, let's solve for 3a. 3a = 3(p² + 10p +1), simplifying to 3p² + 30p +3. After adding 2b and 3a, we are able to get 2p + 10 + 3p² + 30p + 3 = 3p² + 32p + 13

Please help me, im about to cry cause im so confused. Please explain this to me

eduard

$\bold{2.5y=5x-5 }$

$\bold{y=\dfrac{5x-5}{2.5} }$

$\bold{y=\dfrac{2.5(2x-2)}{2.5} }$

$\bold{y=\dfrac{\cancel{2.5}(2x-2)}{\cancel{2.5}} }$

$\bold{ y=2x-2 }$

Si camilo tiene 6 años mas que juan, juan tiene 7 años menos que andrés y andrés tiene 35 años

lidiya [134]

Answer:

Part a) Camilo is 34 years old and Juan is 28 years old

Part b) The difference between Camilo's age and Juan's age is 6 years

Part c) The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

Step-by-step explanation:

The question in English is

If Camilo is 6 years older than Juan, Juan is 7 years younger than Andrés and Andrés is 35 years old .

Part a) How old is Camilo and how old is Juan? raises the equation.

Part b) What's the difference between Camilo's age and Juan's age?

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Part a) How old is Camilo and how old is Juan? raises the equation.

Let

x -----> Camilo's age

y -----> Juan's age

z -----> Andres's age

we know that

$x=y+6$ -----> equation A

$y=z-7$ -----> equation B

$z=35$ -----> equation C

Find the value of y

substitute the value of z in the equation B

$y=35-7=28$

Find the value of x

substitute the value of y in the equation A

$x=28+6=34$

therefore

Camilo is 34 years old and Juan is 28 years old

Part b) What's the difference between Camilo's age and Juan's age?

Subtract Juan's age from Camilo's age

$x-y=34-28=6\ years$

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Adds Camilo's age and Juan's age

$x+y=34+28=62\ years$

$62\ years\neq 65\ years$

therefore

The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

G(x)=\sqrt{x+3}g(x)= x+3 g, left parenthesis, x, right parenthesis, equals, square root of, x, plus, 3, end square root What i

Aleks04 [339]

Answer:

The domain of g(x) is -3 to infinity

Step-by-step explanation:

Given

$g(x) = \sqrt{x + 3}$

Required

Determine the domain of g(x)

We start by expressing the content of the square root in the following form:

$x + 3 \geq 0$

Subtract 3 from both sides

$x + 3 -3 \geq 0 - 3$

$x \geq 0 - 3$

$x \geq - 3$

This can be expressed using interval notation as follows:

$\{x: -3, infiniti\}$

Hence, the domain of g(x) is -3 to infinity
