I think the answer is around 1.4 as you need to multiply the area by 1/9 after finding the real area.

1. Now consider equations of the form , where a, b, and c are all positive integers and . (a) Create an equation of this form th
tino4ka555 [31]

a) To create an equation

X+X =7

so what's X over here is

7² = x²

X=3.5

b) Real numbers are mixture of irrational and rational numbers so √5 and √6 are irrational where as 5 and 6 are not but they two are equal to each other.

Explaining the equation:

√5 +√6 = √11

5 +6 = 11

√11 =11

√= 11 ÷ 11

√= 1

So if root is 1 then -1 is -√

this is the answer propably

Your teacher writes the fact below on the board.Using only mental math, will the answer be less than or greater than 5? How do y
Levart [38]

Answer:

Less than 5

Step-by-step explanation:

The eason behind the answer being less than 5 is because if you multiply something by a fraction that is less than a whole number, then you will get less than the original number you multiplied the fraction with.

Hope this helps :)

Find the lengths of BC and XZ and the measure of BZX
Ann [662]
BC = 12; XZ = 8; BZX = 55

To find BC:
Since XY is the bisector of AB and AC, this means that it is a median of triangle ABC.  Its length will be half of the length of BC; 6 = 1/2BC; 6*2 = BC; 12 = BC

To find XZ:
Since XZ is the bisector of AB and BC, this means that it is a median of triangle ABC.  Its length will be half of the length of AC; 1/2(16) = 8.

To find BZX:

XYCZ is a parallelogram.  Consecutive angles of a parallelogram are supplementary; 180-55=125=XZC.

XZC and BZX form a linear pair and are thus supplementary.  This means that BZX = 180-XZC = 180-125 = 55

8. Use the general formula for an exponential function, f(x) = a. b, to write a specific function given an
Doss [256]

Answer: f(x) = 61(3.5)^x

Step-by-step explanation:

This is what the variables always mean in the function:

a = initial value

b = growth factor

x = time

Then, you just plug them in! Hope this helps.

Prove that if n is an even integer, then n + 1 is odd. Give a proof by contraposition of this theorem.
S_A_V [24]

Answer:

Proved below

Step-by-step explanation:

If we assume that n + 1 even when n is even, it means that;

n + 1 = 2x

Where x is an integer

Then;

n = 2x - 1

This means that n is odd because 2x - 1 is odd.

But we know that n is even, thus, our assumption is wrong.

Therefore, n + 1 is odd when n is even.
