Answer:

a, c, and e

Step-by-step explanation:

$(a) b+b+b+b = 4b\\\\(b) b+4 = 4+b\\\\(c) 2b+2b = 4b\\\\(d) b*b*b*b = b^4\\\\(e) b/\frac{1}{4} = b*4 = 4b\\\\$

(a), (c), and (e) is equivalent to 4b.

Write each number as a logarithm with base 3.

Ksenya-84 [330]

Log3(x)=0 so 3^0=x which is 1
log3(x)=-2 so 3^-2=x which is 1/9
log3(x)=4 so 3^4=x which is 81
This is possibly the answer

Let us say the two numbers are x and y and x>y.

The data we have are;

Difference between the numbers are 12.

3 times larger number is equal to 7 times smaller number.

Then we can write;

----(1)

----(2)

From (1) we can say

Then substituting to (2) gives;

Then;

Please answer the question

Answer:

D. 2x² + 10xy + 8x² because (2x+ 2y) by (x + 4y)

Step-by-step explanation:

Let's mark the sides of the big square as x and a small square as y

See attached picture below

Then we will have the sides of the rectangle:

x + x + y + y = 2x + 2y
and
x + y + y + y + y = x + 4y

The area of the figure is:

A = lw
A = (2x+ 2y)(x + 4y)
= 2x² + 8xy + 2xy + 8y²
= 2x² + 10xy + 8x²

Correct option is D.

Multiply. Reduce to lowest terms. 3/7×4/5=

Andre45 [30]

Answer:

3/5

Step-by-step explanation:

First, multiply both tops and both bottoms so you have one fraction.

Reduce by dividing top and bottom by the same number.

$\frac{3}{4}X\frac{4}{5} = \frac{12}{20} = \frac{3}{5}$

12/20 becomes 3/5 because:

12÷4 =3

20÷4=5

Top and bottom are divided by same "scale factor", 4.

3 and 5 do not have any common factors other than 1, therefore 3/5 is the lowest term.
