I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a

Step-by-step explanation:

LCM=1320

(GDC) HCF=12

Another no.=132

let second no. be =A

According to question

First no.×Second no.=HCF×LCM

6 m from the pole from base of a telephone pole and 10 m to reach the top of the pole how tall is the telephone pole

Answers

Answer:

Explanation

The set up is a right triangle

Given

The distance of pole from the base = 6m

Length of the pole = 10m

Required

Height of the telephone pole h

Using the pythagoras theorem;

hyp^2 = opp^2 + adj*2

10^2 = 6^2 + h^2

h^2 = 10^2 - 6^2

h^2 = 100 - 36

h^2 = 64

h = √64

h = 8m

Hence the height of the telephone pole is 8m

Answers

Answer:

Sue started the day with $260 in her bank account.She purchased 15 books that we're all the same price.After she left the store,she had -$10 in her account.How much did each book cost?

Answers

Answer:

Since she ended up with -$10 in her account after leaving the store, that means that she spent $270 at the store total.

Since the books were the same price, just divide.

270/15=18

This means that each book cost $18

8a The following three shapes are based only on squares, semi circles, and quarter circles. find the perimeter and the area of each shaded parts. Give your answers as completely simplified exact value in terms of pi (no approximations). I NEED THE ANSWER NOW, FIND AREA.

Answers

Answer:

Step-by-step explanation:

The area is 32[tex]\pi[/tex]-64cm^2

if you look at it, ADC makes a quarter circle and so does ABC, so:

area of a circle:[tex]\pi[/tex]r^2 so

then since it’s a quarter circle, divide by 4 which gives you 16[tex]\pi[/tex]

and since there are 2 quarter circles 16[tex]\pi[/tex](2) gives you 32

then you find the area of the square: 8(8) gives you 64 so to find shaded area subtract 64 from 32[tex]\pi[/tex] and that’s the answer

Combine Like Terms : 4x-8-8

Answers

Answer:

4x-16

Step-by-step explanation:

When combining like terms you combine the constant terms (the terms without a variable) and the x terms. Since the only variable term is 4x we can leave in at that.

But there are two constant terms -8 and -8, together they make -16 so, the simplified expression would be 4x-16

OAB is a sector of a circle with centre O and radius 8 cm.
Angle AOB = e°
The area of the sector is 58 cm2
Calculate the perimeter of the sector.
Give your answer correct to 3 significant figures.

Answers

Answer:

The perimeter of the sector is :30.5 cm

Step-by-step explanation:

Mathematically, we have the area of the sector as;

e/360 * pi * r^2

r is 8 cm

so we have

58 = e/360 * pi * 8^2

58/64 * 360/pi = e

e = 103.85

To get the perimeter,

we have length of the arc plus 2r

Length of the arc is;

e/360 * 2 * pi * r

add 2 r;

e/360 * 2 * pi * r + 2r

so we have

103.85/360 * 2 * pi * 8 + 2(8)

= 14.5 + 16

= 30.5 cm

The Supreme Court ruled that the Constitution granted the federal government control over interstate commerce. What Supreme Court case was this? Please help me guys!!!!Introduction: In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The results of this program are shown in the following table.1. Describe what happened to the deer and wolf populations between 1971 and 1980. How did the number of wolves affect the number of deer?2.What do you think would have happened to the deer on the island had wolves NOT been introduced?
