Which expression is equivalent to (4√a²b)(3√b)?
a) 2ab√3
b) 3a²b²
c) 12ab
d) 12ab²
Answer:
A, is close to being correct, I'm not sure if 1 is missing from it, but it should be A, if 1 is missing on purpose then I am wrong.

what's the question
A pink gold bracelet weighs 60 g. It is made from 76% gold, 18% copper and 6% aluminium.
a What is the mass of the gold in the bracelet?
b What is the mass of the copper in the bracelet?
Answer:
m(Au)=45.6 [gr] ; m(Cu)= 10.8 [gr].
Step-by-step explanation:
the masses of gold (Au), copper (Cu) and aluminium (Al) are:
0.76*60=45.6 (gr); 0.18*60=10.8 (gr.) and 0.06*60=3.6 (gr).

-3 + 6 = 2x - 24
a: -30
b: -6
c: 6

Answer:
The answer should be 13.5. but it was not given.
Step-by-step explanation:
[tex] - 3 + 6 = 2x - 24 \\ 3 = 2x - 24 \\ 24 + 3 = 2x \\ 27 = 3x \\ \frac{27}{3} = x \\ 13.5 = x \\ [/tex]

Answer:
(x + 7)(3x - 1)Step-by-step explanation:
See the steps below:
3x² + 20x - 7 = 3x² + 21x - x - 7 = 3x(x + 7) - (x + 7) = (x + 7)(3x - 1)First Method: (By splitting the middle term)
We have to find p and q such that p+q = 20 and
pq = 3×(-7) = -21
Let us looks for the pair of factors of -21 such that their sum is 20 and product is -21.
20 = 21 - 1 and -21 = 3(-7)
∴ 3x² + 20x - 7 = 3x² + 21x - 1x - 7
= 3x(x + 7) -1(x + 7)
= (x + 7)(3x - 1)
Second method: (Using the factor theorem)
The value of y is directly proportional to the value of x.
If y = 10 when x = 5, what is the value of the following.
a) find the value of y when x is equal to 4.
b) find the value of x when y is equal to 6
Answer:
a) find the value of y when x is equal to 4.
Step-by-step explanation:
Answer:
a) the value of y will be x=5 - 4= 1
therefore y=1
b) the value of x will be y= 10 - 6= 4
therefore x=4

Determine whether the ordered pair is a solution of the linear equation y = 11r - 4 (0 -4)
Hi there!
»»————- ★ ————-««
I believe your answer is:
Yes, it is a solution.
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
I am assuming that 'r' is supposed to be 'x'.
⸻⸻⸻⸻
[tex]y=11r-4\\------------\\\rightarrow -4 = 11(0) - 4\\\\\rightarrow -4 = 0 -4\\\\\rightarrow \boxed{-4=-4}[/tex]
⸻⸻⸻⸻
The ordered pair is a solution. You can also tell that it is a solution because the equation given is in slope-intercept form, and '-4' is in b's spot.
⸻⸻⸻⸻
[tex]y = mx+b[/tex]

m^ 2 + m − 90 factorize
Answer:
(m+10)(m-9)
Step-by-step explanation:
To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.
Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)
Answer:
[tex](m-9)(m+10)[/tex]
Step-by-step explanation:
When you are given an expression in this format
[tex]ax^2+bx+c[/tex]
You must find two numbers that add up to b while the product is c.
You do trial and error to figure it out for your equation.
[tex]m^2+m-90[/tex]
Hmm... what two numbers add up to 1 and multiplied together equal -90.
Start off with pairs that can equal 90.
45 2
18 5
9 10
Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!
18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.
9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!
Now use the two numbers and put it in factored form.
[tex](m-9)(m+10)[/tex]

The area of a square is 676 square root. what is the perimeter of the square?
Answer:
the perimeter of the square is 104
Step-by-step explanation:
to find the perimeter of a square we need to use the formula P = 4a
P is perimeter and a is the side of the square
if a is the side and the formula of Area is A = a^2
that means the side of the square is a = 26 because 26 * 26 = 676
now we take 26 and place it in the a spot of the perimeter formula
P = 4 * 26 (P = 104)
can i get brain if this helps and is correct plz and thxs <(^w^)>
Answer:
It's 104
Step-by-step explanation:
[tex] \sqrt{676 = 26} [/tex]Square perimeter formula : P=4×aP=4×aP=4×26P=104Evaluate the expression for x = -2, y = 3, and a = -4

= -28 + 12
= -16
Therefore, your answer is: -16
