b. Factorize using middle term break 3d2 - 16dc – 12c2
Step-by-step explanation:
Given
3d² - 16dc - 12c²
Using middle term break
= 3d² - (18 - 2 )dc - 12c²
= 3d² - 18dc - 2dc - 12c²
= 3d( d - 6c) - 2c( d - 6c)
= ( d - 6c) ( 3d - 2c)
Hope it helps and have a great day onwards ❤
Answer:
= 3d² - (18 - 2 )dc - 12c²
= 3d² - 18dc - 2dc - 12c²
= 3d( d - 6c) - 2c( d - 6c)
= ( d - 6c) ( 3d - 2c)

5.1 is 102% of what number?
Answer:
it is 5
Step-by-step explanation:
102% x 5 =5.1
if you times each answer with you percentage you get the answer
Using the principle of percentage approximation, the value of the number, n is 5
Let the number = n
We then write the expression thus :
(102/100) × n = 5.1
1.02n = 5.1
n = 5.1 / 1.02
n = 5
Therefore, the number, n in which 102% gives a value of 5.1 is 5

Round
your
answer to the nearest cent.
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 (1.015)^t
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P = e^{(2.197+.0149t)}

Answer:
x = 0
Step-by-step explanation:
If one were to fold this figure in half over the line x = 0, then one would end up with a single figure, with no overhang. Hence x = 0 is the line of symmetry. Note; x = 0, can also be called the y-axis.
Answer:
Option D) x = 0
Step-by-step explanation:
Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object. Here we see that the object's Axis of symmetry is the line x =0
The line x = 0,1,2,3,4,5,..... and so on are all vertical lines and
The line y=0,1,2,3,4,5,..... and so on are all horizontal lines
In this this case the line x = 0 is the Axis of symmetry which divides the object in two equal halves.

Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE
Step-by-step explanation:
Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72
On dividing a natural number by 13, the remainder is 3 and on dividing the same number by 21, the remainder

9514 1404 393
Answer:
4
Step-by-step explanation:
The least common multiple of 13 and 21 is 274, so the number of interest will be 10 less than that. The value in the given range is ...
2(274) -10 = 536
We are interested in the remainder from 536/19, which is 4.

8+3m= -7
3m= -7-8
3m= -15
How to verify this answer
Answer:
see below
Step-by-step explanation:
8+3m= -7
Subtract 8 from each side
3m+8-8= -7-8
Combine like terms
3m= -15
Divide each side by 3
3m/3 = -15/3
m = -5
Check
8+3m= -7
8+3(-5) = -7
8-15 = -7
-7 = -7
m = -5 is the solution
Step-by-step explanation:
8+3m=-7
3m= -7-8
3m=-15
m= -5

a number c minus 4.3 is no less than 16. write this word sentence as an inequality.
ill give brainliest
Answer:
c - 4.3 > 16
(hope this helps)
The inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.
What is inequality?The relationship between two values that are not equal is described by inequalities. Equal does not necessarily mean unequal. The "not equal symbol" is typically used to denote that two values are not equal.
As the condition is suggesting c - 4.3 is no less than 16 means it is greater than 16,
So, c - 4.3 > 16
Therefore, the inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.

A rectangle and an equilateral triangle have the same perimeter. The perimeter of the rectangle is 6 ( 1 2 x + 5 ) inches. The perimeter of the triangle is 4 ( x − 2 ) inches. What is the perimeter of each figure?
Answer:
-328/34
Step-by-step explanation:
Here,
Perimeter of rectangle = 6(12x+5)
Perimeter of equilateral triangle = 4(x-2)
Since they are equal, 6(12x+5) = 4(x-2)
or, 72x + 30 = 4x - 8
or, 68x = -38
or, x= -38/68 or -19/34
Now,
Area of triangle ( or rectangle whichever you prefer)
= 4* -19/34 - 8
= -76/34 - 8
= - 328/34
