Answer 1

Answer:

[tex](x - y)(x + y + 1)[/tex]

Step-by-step explanation:

[tex]x(x + 1) - y(y + 1)[/tex]

Lets expand it.

[tex] = > {x}^{2} + x - {y}^{2} - y[/tex]

Lets re-arrange it.

[tex] = > {x}^{2} - {y}^{2} + x - y[/tex]

[tex] = > (x + y)(x - y) + 1(x - y)[/tex]

Lets take (x - y) common.

[tex] = > (x - y)[(x + y) + 1] [/tex]

[tex] = > (x - y)(x + y + 1)[/tex]

david=x+1.50

x+(x+1.50)=940

x=940-x-1.50

2x=940-1.50

2x=938.5

Diagram shows the composite solid formed by a cuboid and a right prism. Trapezium LMNP is the uniform cross section of the prism. It is given the volume of the composite solid is 444cm³. Calculate the length, in cm of MN​

Answers

Answer:

MN = 7 cm

Step-by-step explanation:

Well the volume we can separate into pieces

first the ABCDEFGH (? you know this cuboid)

which has a volume of

[tex]V = AB\cdot BC\cdot CH\\\\V = 3*6*(3+JY+4)[/tex]

if you ask where does the 4 come from

it comes from LP = KB = YC and JY + YC =JC

so

[tex]V = 18(7+MX)[/tex]

this is because JY = MX

the other volume is of BCNPKLXY (hope you understand which one)

and the volume is

[tex]V = BP*PN*NX\\\\V=8*6*4\\\\V = 192[/tex]

and the last one is KYXLMJ (the top "triangle")

the volume is

[tex]V = \frac{LX*XM}{2}*LK\\\\V = \frac{6*MX}{2}*8\\\\V= 6*4*MX\\\\V=24MX[/tex]

so now add them up

and has to equal 444

[tex]V_T = 18(7+MX)+192+24MX\\\\V_T = 126+18MX+192+24MX\\\\V_T = 318+42MX\\\\444=318+42MX\\\\444-318=42MX\\\\126=42MX\\\\MX = 3[/tex]

and finally we know that MN = MX + XN = 3+4 = 7

so here is our answer MN = 7 cm

a couple of notes

[tex]1.\:\angle LXM = 90\\\\2.\:\angle KYX = 90[/tex]

3. the units don't matter due to the fact that everything is in cm

4. see the picture below to get a better idea of which prism I am talking of

5. tell me if you have questions :D

what is 4 to the 7th power

Answers

Answer:

16384

Step-by-step explanation:

The solution for 4 to the 7th power can be expressed as 16,384.

What is 4 to the 7th power?

To calculate 4 to the 7th power, we need to multiply 4 by itself seven times. Let's break it down step by step:

4¹ = 4 {4 to the power of 1}

4² = 4 x 4 = 16 {4 to the power of }

4³ = 16 x 4 = 64 {4 to the power of 3}

4⁴ = 64 x 4 = 256 {4 to the power of 4}

4⁵ = 256 x 4 = 1024 {4 to the power of 5}

4⁶ = 1024 x 4 = 4096 {4 to the power of 6}

4⁷ = 4096 x 4 = 16384 {4 to the power of 7}

Therefore, 4 to the 7th power has a solution equal to 16,384.
