The answer is 410.

How?

A+B =CD

C=(A-B) , D(A+B)

5 + 3 = (5-3)(5+3) = 28

9 + 1 = (9-1)(9+1) = 810

8 + 6 = (8-6)(8+6) = 214

similarly

7 + 3 = (7-3)(7+3) = 410

Answer:

410 is the answer

Step-by-step explanation:

subtract the two digits to get the left most digit of the solution. then add the two digits to get remainder of solution.

ex as we know 5-3=2 and 5+3=8 in the given question

5 + 3 = 28

True or false? A circle could be circumscribed about the quadrilateral below.
sergij07 [2.7K]

A circle can be circumscribed about a quadrilateral if and only if the opposite angles of the quadrilater sum up to 180.

This is not the case, so you can't circumscribe a circle about the quadrilateral.

Mohamed decided to track the number of leaves on the tree in his backyard each year. the first year, there were 500500500 leaves
VARVARA [1.3K]

Mohamed decided to track the number of leaves on the tree in his backyard each year. the first year, there were 500 leaves. each year thereafter, the number of leaves was 40% more than the year before. let f(n) be the number of leaves on the tree in Mohamed's backyard in the n^th year since he started tracking it. f is a sequence. what kind of sequence is it?

Number of leaves on the tree in first year = 500

The number of leaves was 40% more than the year before.

So rate of increase is 40/100 = 0.4

We use exponential growth formula,

f(n) = a(1+r)^n

Where a is the initial number, r is the rate of growth, n is the number of years

We know a= 500, r= 0.4

f(n) = 500(1+0.4)^n

f(n) = 500(1.4)^n

Plug in n=1,2,3...

f(1) = 500

f(2) = 500 * 1.4^1

f(3) = 500 * 1.4^2 and so on

From this we can see that the common ratio is 1.4

Hence it is a Geometric sequence.

In the figure, PQ is parallel to RS. The length of PQ is 2 cm; the length of
Rashid [163]

Answer:

Step-by-step explanation:

Parallel lines in this kind of triangle are always in a strict ratio of small to large or large to small based on how you look at it. So we have 4cm to 6cm, which is 2:3 ratio. We know the smaller side, but want the larger side, so we can set up 2/3 = 10/? the ? is 15.

-14(3a+6)=12(6-4a)+12 and steps please
Sunny_sXe [5.5K]

Answer:

In the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28

Step-by-step explanation:

Given equation is -14(3a+6)=12(6-4a)+12

To simplify the given equation:

-14(3a+6)=12(6-4a)+12

Taking all terms to one side

-14(3a+6)-12(6-4a)-12=0

-[14(3a+6)+12(6-4a)+12]=0

Now dividing by negative sign on the above equation we get

14(3a+6)+12(6-4a)+12=0 (using distributive property)

42a+84+72-48a+12=0 ( adding the like terms )

-6a+168=0

-6a=-168

6a=168

a=\frac{168}{6}

Therefore a=28

Therefore in the given equation -14(3a+6)=12(6-4a)+12 the value of a is 28
