Answer:
3x+18
Step-by-step explanation:
6+3(x+4)=6+3x+12
=3x+18
Answer:
Interest = $240
Ending Balance = $990
Step-by-step explanation:
Applying I = prt/100
= (750*4*8)/100
= 240
Therefore Interest = $240
Adding Interest to Principal
= $240 + $750 = $990

The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A=
Where r is the radius of the circle.
Given :
Solving for r we have:

Or r= 10.
The area of a sphere is calculated by the formula :

Substituting r value we have:
SA= 
The total surface area of this sphere is 400π .
Answer:
let the numbet of formal attires with Clara be X
Clara lended susan 1/2 = X/2
Clara buys 4 = X/2 +4
Answer = X/2 + 4
( as the number of formal attires originakly with Clara is not specified)
2 positive unit tiles are needed to complete the factorization.
Given
The partial factorization of x^2 – 3x – 10 is modeled with algebra tiles.
<h3>Partial factorization;</h3>
Partial fractions are the fractions used for the decomposition of a rational expression.
When an algebraic expression is split into a sum of two or more rational expressions, then each part is called a partial fraction.
In the second line, we can see that first term 1 is labeled + x squared, second is labeled +<u> </u><u>2x</u><u> (two positive </u><u>tiles </u><u>above),</u> then the 5 tiles below + x squared are labeled negative x, and the 10 tiles below the + x tiles are labeled negative.
The negative values are represented as tiles labeled below (negative tiles) while positive values are tiles labeled above (positive tiles).
Therefore,
The factorization is;

Hence, 2 positive unit tiles are needed to complete the factorization.
