Answer:
D
Step-by-step explanation:
You first add 4 to all of the numbers giving you 7, 24, 41, and 49. Only choice D is a perfect square. for reference, 7*7=49
Answer:
45
Step-by-step explanation:
basically what we are trying to find is x + 4= square
for you to understand this better, take eg 5.
5 + 4 = 9
| \
four less than the square number( 9 is the square of 3)
we took the square of 3 and subtracted 4 from it making the result 4 less
12 + 4 = 16
| \
four less than the square number( 16 is the square of 4)
we took the square of 4 and subtracted 4 from it making the result 4 less
understanding that,
a)3
3 + 4 = 7
there is no square root of 7 X
b)20
20 + 4 = 24
there is no square root of 24 X
c)37
37 + 4 = 41
there is no square root of 41 X
d) 45
45 + 4 = 49
the square root of 49 = 7
answer=49

Step-by-step explanation:
Answer:
To change a percent to a decimal we divide by 100. This is the same as moving the decimal point two places to the left. For example, 15% is equivalent to the decimal 0.15.
Step-by-step explanation:
f(x) = 2x - 7
g(x) = 2x2 + 2x – 7
Find: f(g(x))
hi
you must find f°g
so apply g then f.
g(x) = 2x²+2x-7
f(x) = 2x-7
so f(gx) = 2 ( 2x²+2x-7) - 7
= 4x²+4x-14-7
= 4x²+4x - 7

What is 3/4 of 4/5. Plz help
Answer:
3/5
Step-by-step explanation:
We want to find 3/4 of 4/5.
The keyword of tells us that we need to multiply. Therefore:
[tex]\frac{3}{4}\times\frac{4}{5}[/tex]
Multiply:
[tex]=12/20=3/5[/tex]
So, 3/4 of 4/5 is 3/5.
We can confirm this by converting them to decimals.
4/5 is 0.8.
3/4 is 0.75.
0.75 or 75% of 0.8 is indeed 3/5 or 0.6.
What is the value for y?
Answer:
-8
Step-by-step explanation:
We have a given x-value of -2 at the side.
We can plug that in to the equation y = 3x -2 to get an output/y-value
y = 3x -2
y = 3(-2) -2
y = -6 -2
y = -8

The amount of oil used in four different recipes is shown in the table. Recipe Oil Bread 2/8 cup Cookies 1/3 cup Cake 1/5 cup Pie 1/7 cup Which recipe uses the most oil? bread cookies cake pie
Answer:
cookie
Step-by-step explanation:
Answer: I think that the answer is cookies.
Step-by-step explanation:
The least common denominator for the fractions would be 840.
Bread: 2/8 x 105/105 = 210/840
Pie: 1/7 x 120/120 = 120/840
Cookies: 1/3 x 280/280 = 280/840
Cake: 1/5 x 168/168 = 168/840
Least to greatest:
120/840, 168/840, 210/840, 280/840
That is how I know that the cookies use the most oil.
