find the value of a²+b when a =-2 and b=5
Answer:
4+5=9
Step-by-step explanation:
a2+b=9
Two negatives equal a positive you multiply 2, 2 times because of the power 2.
Answer:
[tex]\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: Solution \Longrightarrow 9 }}}}}}}}[/tex]
Step-by-step explanation:
Given,
a = - 2
b = 5
Our expression is,
a² + b.
To solve this, we need to substitute the values of a & b in the given expresssion. So,
a² + b
= (-2)² + 5
= 4 + 5 (2 negatives when mutilpied gives a positive number)
= [tex]\boxed{\sf{9}}[/tex]

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
What value of b will make the equation a true statement? Explain how you arrived at your solution. (−34 + 43)+ b = 0
Answer:
b = -9
Step-by-step explanation:
Given the equation (−34 + 43)+ b = 0
We are to find the value of b
First solve for the value in parenthesis
(−34 + 43)+ b = 0
9+b = 0
Subtract 9 from both sides
9+b-9 = 0 - 9
b+0 = -9
b = -9
Hence the value of b will make the equation a true statement is -9
2, en un curso de 37 estudiantes se proponen a elaborar un cohete con material reciclado, para poder hacer los cohetes, en el curso se cuenta con 151 tubos de cartón que se recolectaron en una jornada de reciclable. A: si para hacer un cohete se necesitan 4 tubos de cartón, ¿Hay suficientes tubos para que cada estudiante elabore su cohete?
Answer:
Yes, there enough tubes for each student to make their rocket.
Step-by-step explanation:
Given - In a course of 37 students they propose to make a rocket with recycled material, in order to make the rockets, in the course there are 151 cardboard tubes that were collected in a recyclable day.
To find - If 4 cardboard tubes are needed to make a rocket, are there enough tubes for each student to make their rocket ?
Proof -
Given that,
1 rocket is made with 4 cardboard tubes
Total cardboard tubes = 151
Now,
1 student will make 1 rocket
Total students = 37
⇒Total rockets made by the course = 37
Now,
1 rocket used 4 cardboard tubes
⇒37 rocket used 37×4 cardboard tubes
⇒37 rocket used 148 cardboard tubes.
As
148 < 151
⇒There are enough tubes for each student to make their rocket.
A TV has a listed price of $616.99 before tax. If the sales tax rate is 9.75%, find the total cost of the TV with sales tax included. Round your answer to the nearest cent, as necessary.
Answer:
The sales tax is determined by computing a percent of the purchase price. To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price.

Answer: 3.6
Step-by-step explanation:
Using pythagorean we can determine that a^2+b^2=c^2
In this case the leg and adjacent make a distance of 2 and 3 we can substitute for a and b so
[tex]2^{2}+3^{2}=c^{2}[/tex]
13=[tex]c^{2}[/tex]
c= 3.605 rounded is 3.6

Which of the following expressions represents the value, in dollars, of a certain number of dimes, d, and pennies, p?
Answer:
If your answer choices are:
0.01d + 0.10p
0.10d + 0.01p
0.11dp
0.11d + p
A dime is 10% of a dollar and a penny is 1% of a dollar, or 0.10 and 0.01
Then 0.10d + 0.01p is the expression

16x−12−24x+4
Explain your reasoning.
Answer:
-8x-8
Step-by-step explanation:
Since 16x and -24x have like variables, we can subtract to get -8x. Then, we can add the constants to get -8.
Step-by-step explanation:
16x-12-24x+4
=16x-24x-12+4
=8x-8

Answer:
3) x = −11
4) x = 40/11 or 3.636363... (it keeps going)
5)
Step-by-step explanation:
3) 5x/6 − ( 2x − 1/2 ) + 4 − 2x/3 = 11
Step 1: Simplify both sides of the equation.
5x/6 − ( 2x−1/2 ) + 4 − 2x/3 = 11
5x/6 + − x + 1/2 + − 2/3x + 4/3 = 11 ( Distribute )
5/6x + − x + 1/2 + − 2/3x + 4/3 = 11
( 5/6x + − x + − 2/3x ) + ( 1/2 + 4/3 ) = 11 ( Combine Like Terms )
−5/6x + 11/6 = 11
Step 2: Subtract 11/6 from both sides.
−5/6x + 11/6 − 11/6 = 11 − 11/6
−5/6x = 55/6
Step 3: Multiply both sides by 6/(-5).
( 6/−5 ) * ( −5/6x ) = ( 6/−5 ) * ( 55/6 )
x = −11
4) 10 - 2x = 3/4x
x = 40/11
(going to also be long I so wont put my work here)
5) -3( x - 3 ) - 9x - 9 = 4( x + 2 ) - 12
x = 1/4
(again, is long so wont put work)

Answer:
A: 6x^2 + 19x + 3
Step-by-step explanation:
6x + 1 (x +3)
use the foil method so first do 6x(x) and you get 6x^2 then 6x(3) + x(1) and you get the 19x then you just do 3(1) and you get your answer which as stated above is 6z^2 + 19x + 3
