barry has 18 more marbles than heidi.if barry has 92 marbles,write and solve an equation to determine the number of marbles heid
Basile [38]
N= Heidi's marbles
92 - n =18   (Barry's 92 marbles - whatever Heidi has = 18 marbles difference)

92 -n +n = 18 +n   (I added n to each side)
92 = 18+n    
 92 -18 = 18-18 + n   (I subtracted 18 from both sides)
74 = n    Heidi has 74 marbles

A square has side length represented by X +4 inches write an expression to represent the area. Express your answer as a trinomia
romanna [79]

Answer:

A=(x^2+16+8x)\ \text{inches}^2

Step-by-step explanation:

Given that,

The side length of a square, l = (x+4) inches

We need to find an expression to represent the area of the square.

The area of a square is given by :

A=\text{side}^2

So,

A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2

So, the area of the square is (x^2+16+8x)\ \text{inches}^2.

Rewrite the slope intercept equation of the line y = 2x + 5 in standard form. A) 2x - y = -5 B) 2x + y = 5 C) -2x - y = -5 D) 2x
goldenfox [79]

Answer:

(A) 2x-y=-5

Step-by-step explanation:

Slope intercept form of equation of line is y = mx+c \ where\ m\ is \ slope

The standard form of equation is Ax + By + C = 0

Now let m=\frac{A}{B}therefore, m =\frac{2}{1}\ which\ gives\ A = 2and\ B = 1  

substituting the value of A and B  in slope intercept form,

y = \frac{A}{B} x+5\\\y = \frac{2}{1} x+ 5\\By\ simplifying,\\1y = 2x + 5\\on\ rearranging\ the\ above\ equation \\2x-y=-5\\which\ gives\ a\ standard\ form\ of\ equation\ Ax +By +C= 0\ where\ A= 2,\ B= (-1)\ and\ C = 5
