Use the distributive property to create an equivalent expression too 8(2j + 9 + j).

Answer:

(half of base)² + (height)² = (20)²

Step-by-step explanation:

In an isosceles triangle, the angle bisector from the 3rd angle to the opposite side is a perpendicular bisector, so you split the isosceles triangle into two congruent right triangles.

This technique of 'splitting the isosceles' is used a LOT.

Answer:

this is a right angle triangle with a 45 degree angle so ew has to be the same length as qe so 7 and then a square + b squared= c squared gets you the hypotenuse 9.89 with proper sig figs you get 10

Answer:

12-8+3 for the numerical and 2x=3y-6 for the algebraic expression

Step-by-step explanation

Numerical expression consists of numbers and one operation

Algebraic expression consist of multiple varaibles  and constents

Answer:

algebraic expression: 6p +18

1: 121, 2: 59, 3: 59

This is for the first graph because if you look at the bottom half of a circle is 180 so since one is 121 you just have to subtract 121 from 180 and you have your answer

Answer:

62

Step-by-step explanation:

Since you know that JK + KL = JL, this would be:

27 + 3x - 1 = 5x + 2

Now, solve this equation:

combine like terms first

[tex]26+3x=5x+2[/tex]

subtract 3x from both sides

[tex]26 = 2x+2[/tex]

subtract 2 from both sides

[tex]24 = 2x[/tex]

divide both sides by 2

[tex]12 = x, x= 12[/tex]

Since you want to find JL and JL = 5x + 2, plug x = 12 into that equation.

[tex]JL = 5* 12 + 2\\JL = 60 + 2\\JL = 62[/tex]

Answer:

84

Step-by-step explanation:

To complete the concrete highway with pavers 84 pavers are needed.

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

From the given information each Pavel has an area of 4.5 square feet.

And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,

= (21×18) sq feet.

= 378 sq feet.

Therefore, The number of pavers needed is,

= (378/4.5).

= 84 pavers.

Answer:

D. 2019

Step-by-step explanation:

So I started by rewriting the function f(x)

1000 = 10^3 so

    f(x)=10^3 times 1.03^x

1.03 = 103/100 so

     f(x)= 10^3 times (103/100)^x

to raise a fraction to a power you just raise the numerator and denominator to that power so

      f(x)= 10^3 times 103^x/100^x

change it to exponential form with a base of 10

     f(x)=10^3 times 103^x/10^2x

then you can reduce it with the 10^3

     f(x)=103^x/10^2x-3

so now that thats in more of a standard form you can find the intersection of the two functions

which is at (9.012,1305.244)

x is the number of years after 2010, so they will be equal ~9 years after 2010, which is 2019.

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Answer:

25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.
