Evaluate the expression ab2 + 2ab + a2 for a = 6 and b = 3.
a) 128
b) 126
c) 130
c) 124
Answer:
I believe there is an error with the problem
Step-by-step explanation:
3*6*2 + 2*6*3 + 6*2 = 36+36+12 = 84
The answer of the expression ab² + 2ab + a² for a = 6 and b = 3 will be 126 so option (b) will be correct.
What is an expression?
A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
Given the expression
ab² + 2ab + a²
Now,
a = 6 and b= 3
So,
⇒ 6(3)² + 2(6)(3) + 6²
⇒ 36 + 54 + 36
⇒ 126
Hence "The answer of the expression ab² + 2ab + a² for a = 6 and b = 3 will be 126".

Answer:
30; -5 is 5 units away from 0 and V is 25 units away from 0, and 5 + 25 = 30.
Step-by-step explanation:
To find the distance between point T, which has a value of -5, and V, which has a value of 25, we should find the absolute value of each number and then add those numbers together.
So, the absolute value of -5 is 5 and the absolute value of 25 is 25. 25 + 5 = 30, and this is the length of TV.

A line passes through the point (−3,−10) , and it’s perpendicular to the line y=0 . Find an equation for this line.
Answer:
Step-by-step explanation:
y = 0 is actually the x axis.
All the points on the line you want have an x value of - 3
-3,-10 is actually one of those points
The equation you want is x = - 3
Solve for h in the mathematical formula A=1/2(a+b)h
Step-by-step explanation:
Since we arent given enough information to SOLVE for h, I will get as close as I can by rearranging the equation for h
Convert the fraction to a decimal for simplicity
A = 0.5(a + b)h
Divide both sides of the equals by 0.5
A/0.5 = (a + b)h
We can convert A/0.5 into its reciprocal
2 A = (a + b)h
Divide both sides of the equation by the bracketed (a + b)
(2 A) / (a + b) = h
Rewritten
h = [tex]\frac{2A}{(a + b)}[/tex]A line passes through the point (6,-4) and has a slope of - 4/3.
Write an equation in point-slope form for this line.
Answer:
Step-by-step explanation:
In point-slope form,
y - y1 = m(x - x1)
m = -4/3
x1 = 6
y1 = -3
y + 3 = (-4/3)(x - 6)

2r + 4s = –12
1) (–4, –8)
2) (–8, –4)
3) (–7, 8)
4) (8, –7)
Answer:
r = 8 and
s = -7
Step-by-step explanation:
(2r + 4s = - 12)/2 =
r +2s = -6
r = -2s - 6
Substitution:
6 (-2s -6) + 7s = -1
-12s - 36 + 7s = -1
-5s = 36-1
s = 35/-5
s = -7
6r + 7(-7) = -1
6r - 49 = -1
6r = 49-1
r = 48/6
r = 8

A jewelry store bought a gold necklace and marked it up 110% from the original cost of $23.52. Later on, Dean purchased the gold necklace and paid 14.75% sales tax. How much, including tax, did he pay for the gold
necklace?
9514 1404 393
Answer:
$56.68
Step-by-step explanation:
The final price is ...
(cost price) × (1 +110%) × (1 +14.75%) = (cost price)×2.10×1.1475
= $23.52×2.40975 ≈ $56.68
Dean paid $56.68 for the necklace.
Kristen babysits 38 hours a week for $6.80 per hour. She earns an additional $224.00 in tips . How much did she make in 1 week?
Answer:
$502.40
Step-by-step explanation:
Kristen works 38 hours for $6.80 per hour.
We multiply her pay and the hours she worked:
38 × 6.8 = 258.4
Thus, she makes $258.40/week
Now we add her tips, which would be the equation 258.4 + 224
258.4 + 224 = 502.4
So, she made $502.40 in 1 week

Rocco loves making spaghetti with his grandmother. They make homemade tomato sauce by adding pureed tomatoes, sugar, salt, olive oil, and water. He notices that after he stops stirring, he sees a greasy film at the top of the red liquid. What does this tell you about his sauce mixture?
Oil floats on water because it is less dense I believe. So that would be the oil on top of the sauce(the oil is on top because of the water that was also added).

Answer:
28/25
Step-by-step explanation:
To make the number into a fraction, multiply and divide by 100:
1.12 × 100/100 = 112/100
Recognize that numerator and denominator have a factor of 4 in common:
112/100 = 28×4/(25×4) = 28/25

HELP PLEASE. which equation describes a line parallel to line g that has a y-intercept at (0, -1)
Answer:
Line C is parallel to the given line.
Step-by-step explanation:
The given graph slopes down, and thus has a negative slope: m = -1/2.
Of the possible choices, only C has this slope: y = (-1/2)x + b. The y-intercepts b and (0, 6) need not be the same, as the quality of parallelness is all that we care about here.
