Drained Reclamation or Deep Cement Mixing? Which one do you think is the better method of land reclamation and why? (Just looking for opinions btw!)

AE:

DE:150

PABCDE: 720

Step-by-step explanation:

We can find AE by the pythagorean theorem,

AE is the hypotenuse so AE=c, and the leg of the triangle would be 150-30=120

c^2=2500+14400

AE=130

We can use the pythagorean theorem again to find DE.

The base would equal 140-50=90 and the height would equal 120

DE^2=22500

DE=150

The perimeter would be 150+140+150+130+150=720

Let me know if somethings wrong

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
