The expression 3x²y + xy² + 2x + 5 has in its entirety 4 term.
First let's define what algebraic expressions are.
Algebraic expressionAn algebraic expression is a set of numbers and letters that make up an expression that has a meaning, the letters are variables and the numbers are coefficients or independent terms, algebraic expressions can be part of an equation and model mathematical processes.
The terms of an expression are identified by the fact that they are separated by means of an addition and subtraction operation:
x + y has two termsAs we can see the expression has addition operations so it has more than 1 term:
1 = 3x²y2 = xy²3 = 2x4 = 5this expression has 4 terms.

Find the perimeter of a room with a length of 28 ft. and a width of 19 ft.
Answer:
98 ft
Step-by-step explanation:
28x2 + 19x2
=98
Answer:
Is the room a rectangle size? If so:
28 + 28 = 56
19 + 19 = 38
56 + 38 = 94 ft.
Opposite sides are parallel and equal:
therefore whenever there is two given lengths make sure to multiply them two times then add them together if only its a rectangle.
if its a square make sure to multiply the given length 4 times.

Riley invested $5,100 in an account paying an interest rate of 7\tfrac{3}{4}7 4 3 % compounded quarterly. Ryan invested $5,100 in an account paying an interest rate of 7\tfrac{1}{4}7 4 1 % compounded daily. After 7 years, how much more money would Riley have in her account than Ryan, to the nearest dollar?
Answer: 257
257 in delta math
Step-by-step explanation:
After 7 years, Riley would $441.5 more have in her account than Ryan.
What is compound interest?Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Given that Riley invested $5,100 in an account paying an interest rate of [tex]7\tfrac{3}{4}[/tex]% compounded quarterly. Ryan invested $5,100 in an account paying an interest rate of [tex]7\tfrac{1}{4}[/tex] % compounded daily, we need to find that after 7 years how much more money would Riley have in her account than Ryan,
[tex]A = P(1+r/n)^{nt[/tex]
Where A = amount
P = principal
r = rate
n = number of times the amount is compounded and t = time
Riley = compounded quarterly,
[tex]A = P (1 + r / 4)^{4t[/tex]
[tex]A = 5100(1+0.019375)^{4(7)}\\\\A = 5100(1.019375)^{28}\\\\\\[/tex]
[tex]A = 8728.13[/tex]
Therefore, in 7 years Riley has $8728.13.
Ryan = compounded daily,
[tex]A = P (1 + r / 365)^{365t[/tex]
[tex]A = 5100(1 + 0.00019)^{356(7)}\\\\A = 5100(1.00019)^{2555}\\\\A = 8286.64[/tex]
Therefore, in 7 years Ryan has $8286.64.
Riley will have $441.5 more.
Hence after 7 years, Riley would $441.5 more have in her account than Ryan.

What is the length of AB⎯⎯⎯⎯⎯? Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth. cm A horizontally-aligned scalene triangle A B C. Side A C is labeled as 18 centimeters. Side B C is labeled as 12 centimeters. Angle C is labeled as 79 degrees.
Answer:
AB = 19.6 cm
Step-by-step explanation:
Let AB be represented by c. Applying the cosine rule, we have;
[tex]c^{2}[/tex] = [tex]a ^{2}[/tex] + [tex]b^{2}[/tex] - 2ab Cos C
= [tex]12^{2}[/tex] + [tex]18^{2}[/tex] - 2(12 x 18) Cos [tex]79^{o}[/tex]
= 144 + 324 -432(0.19081)
= 468 - 82.4299
[tex]c^{2}[/tex] = 385.5701
c = [tex]\sqrt{385.5701}[/tex]
c = 19.6359
The side AB of the given triangle is 19.6 centimetres.

A line passes through the points (-1, 4) and (3, -8). A second line passes through
(-1,8) and (2, 11).
A) Write the equation of each line. Show all work.
Answer:
y = -3x + 1, y = x + 9
Step-by-step explanation:
An equation consists of a slope and the y-intercept. To find the slope, you need to plug the values into the slope formula.
y2 - y1/ x2 - x1
= -8 - 4/ 3 - (-1)
= -12/ 4
= -3
The slope of the first line is -3.
To find the y-intercept, you need to plug in either one of the coordinates into the equation, y = -3x + b
-8 = -3(3) + b
-8 = -9 + b
1 = b
The equation, for the first one, is y = -3x + 1
Line 2:
11 - 8/ 2 - (-1)
= 1
y = 1x + b
11 = 1(2) + b
11 = 2 + b
9 = b
y = x + 9
Match each value to the correct expression.

Which table has a constant of proportionality between y and 2 of 0.6?
Choose 1 answer:
find the slope-intercept equation of the line that passes through (-7,2) and had a slope of 0
Answer: Y=0x+b
Step-by-step explanation:
Y=mx+b is what we need to set it to.
Since we already know the slope, we can go ahead and find the y-intercept to complete the equation
(-7,2), here -7 is the x and 2 is the y value
y=mx+b
plug all the known information now and solve for b (y-intercept)
y is 2, m (slope) is 0, x is -7
2=0(-7)+b
2=0+b
2=b
y=0x+2 or simply y=2
Answer:
y = 2

radius of a cone with a volume of 100.48 yds3 and a height of 6 yds
Answer:
r = 4
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
V = 100.48
h = 6
π = 3.14
Work:
V = πr²(h/3)
100.48 = r²(3.14)(6/3)
100.48 = r²(3.14)(2)
100.48 = r²6.28
r² = 100.48/6.28
r² = 16
[tex]\sqrt{r^2} =\sqrt{16}[/tex]
r = 4
