What multiplies to -26 and adds to -25

jeka57 [31]

Answer:

1 and -26

Step-by-step explanation:

Consider the factors of 26 (because the two numbers have to multiply to -26). These are: 1 and 26, 2 and 13.

2 and 13 cannot be added or subtracted from one another to get -25, but 1 and 26 can, or rather 1 and -26.

Which of the following shows that polynomials are closed under subtraction when polynomial x + 5 is subtracted from 3x2 + 2x − 6

Art [367]

For this case we have the following polynomials:
$P = 3x ^ 2 + 2x - 6

Q = x + 5$
By subtracting both polynomials we have:
$P - Q = (3x ^ 2 + 2x - 6) - (x + 5)
$
What we must do is subtract terms of the same degree.
We have then:
$P - Q = 3x ^ 2 + (2x - x) + (-6 - 5)

P - Q = 3x ^ 2 + x - 11$
Answer:
$3x ^ 2 + x - 11$ will be a polynomial

How do solve this?? please

aksik [14]

Answer:

m = - 3

n = 2

Step-by-step explanation:

It can be solved using laws of exponents as given below:

$5 {x}^{n} y(2 {x}^{4} {y}^{m} ) = \frac{10 {x}^{6} }{ {y}^{2} } \\ \\ (5 {x}^{n} .2 {x}^{4} )(y. {y}^{m} ) = 10 {x}^{6} {y}^{ - 2} \\ \\\cancel {10}\:\: {x}^{n + 4} . {y}^{m + 1} = \cancel {10}\:\: {x}^{6} {y}^{ - 2} \\ \\ {x}^{n + 4} . {y}^{m + 1} = {x}^{6} {y}^{ - 2} \\equating \: like \: terms \: on \: both \: sides \\ \\ {x}^{n + 4} = {x}^{6} \\ \\ \implies \: n + 4 = 6 \\ \\ n = 6 - 4 \\ \\ \huge \red{n = 2} \\ \\ {y}^{m + 1} = {y}^{ - 2} \\ \\ \implies \: m + 1 = - 2 \\ \\ m = - 2 - 1 \\ \\ \huge \purple{m = - 3}$

Can someone please help me, will give brainliest

Ivenika [448]

Answer:

(d) 1 mile = 10 blocks

Step-by-step explanation:

The ballpark is 8 blocks west and 15 blocks north of Jeff's home. The Pythagorean theorem tells us the straight-line distance is ...

d² = 8² +15² = 64 +225 = 289

d = √289 = 17 . . . blocks

The problem tells us this represents 1.7 miles, so the proportion is ...

blocks/miles = 17 blocks/(1.7 miles) = 10 blocks/mile

The map scale is 1 mile = 10 blocks.
