Answer:
Step-by-step explanation:
54 = 6*9
That means there are 3 threes and 1 two
54 = 2*3 * 3 * 3
There are a pair of 3s and a two and a 3 left over.
The two and the three remain under the root sigh.
One of the pair of threes comes out of the root sign.
The other one is thrown away.
sqrt(54) = 3*sqrt(6)
Answer: -2*3 sqrt6)
Answer: - 6 sqrt(6)
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]

[tex] \sf \: - 2 \sqrt { 54 }[/tex]
Factor [tex]\sf54=3^{2}\times 6[/tex]. Rewrite the square root of the product [tex]\sf\sqrt{3^{2}\times 6} [/tex] as the product of square roots [tex]\sf \sqrt{3^{2}}\sqrt{6}[/tex]. Take the square root of [tex]\sf3^{2}[/tex].[tex] \sf-2\times 3\sqrt{6} [/tex]
Multiply -2 and 3 to get -6.[tex] \boxed{ \boxed{ \bf-6\sqrt{6} }}[/tex]
The answer will be [tex]\boxed{\sf-6\sqrt{6} }[/tex]. If you want you can further simplify it to - 14.696..can u help me solve the problem plzzzzz
Step-by-step explanation:
This is the same as

plz someone answer this . DO this question
Answer:
Step-by-step explanation:
a) 64 (A=bh)
b) 96 ((16x12)÷2)
Answer:
Step-by-step explanation:
a) base = AB = 16 cm
height = DX = 6cm
Area of the parallelogram = base * corresponding height to the base
= 16 * 6
= 96 sq. cm
Area of parallelogram = 96 sq .cm
BC * DY = 96
12 * DY = 96
DY = 96/12
DY = 8 cm
-3+x=-8 what is the answer
Answer:
x=-5
Step-by-step explanation:
add 3 to -8
1 Regroup terms.
x-3=-8
x−3=−8
2 Add 33 to both sides.
x=-8+3
x=−8+3
3 Simplify -8+3−8+3 to -5−5.
x=-5
x=−5
Answer: x=−5
A farmer plowed 9/10 of a acre in the morning and 1/2 of an acre in the afternoon. How many acres did the farmer plow in all?
Answer:
7/5
Step-by-step explanation:
Answer:
1[tex]\frac{2}{5}[/tex] of an acre or 1.4 acres.
Step-by-step explanation:
The least common multiple of 10 and 2 is 10.
Convert [tex]\frac{9}{10}[/tex] and [tex]\frac{1}{2}[/tex] to fractions with a denominator of 10.
[tex]\frac{9}{10}[/tex]+[tex]\frac{5}{10}[/tex]
Since these fractions now have the same denominator, add them by adding the numerators.
[tex]\frac{9+5}{10}[/tex]
Add 9 and 5 to get 14.
[tex]\frac{14}{10}[/tex]
Reduce the fraction to the lowest terms by extracting and canceling out 2.
[tex]\frac{7}{5}[/tex]= [tex]1\frac{2}{5}[/tex] =1.4

Write an equation for the following real life scenario.
Use "t" to represent your variable.
Jasmine's cell phone company charges her $35 a month for phone service plus 0.50 for each text message. Her
total bill for the month was $51.
Answer:
[tex]35+0.50t=51[/tex]
Step-by-step explanation:
Since the $35 is a one-time fee, 0.50 is the rate, t is the variable, and 51 is the total bill, we can form the equation:
[tex]35+0.50t=51[/tex]
Answer:
0.50t+35=51
Step-by-step explanation:
0.50 is the amount for each text message so it becomes 0.50t (0.50 × text message). This is added to the monthly cost which is 35 dollars (+35) the question wants an equation as the answer so (=51).

HELP NEEDED !!!
find the unknown angles
please helppppppppppp
Answer:
see explanation
Step-by-step explanation:
Substitute the given values of x into f : x → [tex]\frac{3}{7}[/tex] x + 4
x = - 14 → ([tex]\frac{3}{7}[/tex] × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2
x = 28 → ( [tex]\frac{3}{7}[/tex] × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16
x = [tex]\frac{7}{8}[/tex] → ([tex]\frac{3}{7}[/tex] × [tex]\frac{7}{8}[/tex] ) + 4 = [tex]\frac{3}{8}[/tex] + 4 = [tex]\frac{3}{8}[/tex] + [tex]\frac{32}{8}[/tex] = [tex]\frac{35}{8}[/tex]
x = - [tex]\frac{2}{9}[/tex] → ([tex]\frac{3}{7}[/tex] × - [tex]\frac{2}{9}[/tex] ) + 4 = ([tex]\frac{1}{7}[/tex] × - [tex]\frac{2}{3}[/tex]) + 4 = - [tex]\frac{2}{21}[/tex] + [tex]\frac{84}{21}[/tex] = [tex]\frac{82}{21}[/tex]
Answer:
See below in bold.
Step-by-step explanation:
1. 3/7 * -14 + 4
= -6 + 4
= -2.
2. 3/7 * 28 + 4
= 12 + 4
= 16.
3 3/7 * 7/8 + 4
= 3/8 + 4
= 35/8 or 4 3/8.
4. 3/7 * -2/9 + 4
= -6/63 + 4
= -2/21 + 4
= -82/21 or -3 19/21.
The square below represents one whole.What percent is represented by the shaded area?
You won't type in the percent sign as that's already taken care of
=============================================================
Explanation:
We have 6 squares shaded out of 100 total. This means we have 6/100 = 0.06 = 6% of the squares shaded. The term "percent" means "per 100" or "for every 100".
Take note that there are 10 rows and 10 columns, meaning there are 10*10 = 100 squares total, either shaded or not shaded.

if f(x)=4x-5 what is the value of f(2)
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
Value of Polynomial :The value of a polynomial p(x) or f(x) at x = α is obtained by putting x = α in p(x) or f(x) and it is denoted by p(α) ...!
Required Solution :Let f(x) = 4x - 5
⇒f(2) = 4(2) - 5
= 4 × 2 - 5
= 8 - 5

Answer:
647/ 4.8 ×9.7
Step-by-step explanation:
so what you need to do is 647 round up to 650 because 1-4 you get less but more than 5-9 u get more than that
4.8 becomes 5 and 9.7 becomes 10
650 /5×10
and u ill get 1,300 i hope this hepls u :)

Please help! What is |x-3|=9
Answer:
x = 12 or x = -6
Step-by-step explanation:
Solve for x over the integers:
abs(x - 3) = 9
Split the equation into two possible cases:
x - 3 = 9 or x - 3 = -9
Add 3 to both sides:
x = 12 or x - 3 = -9
Add 3 to both sides:
Answer: x = 12 or x = -6
