Answer:

35 m^2 + 30 m - 5

Step-by-step explanation:

The area of a rectangle can be found by

A = l*w

= (7m-1) ( 5m+5)

FOILing

= (7m*5m) + 7m*5 + -1*5m -5

= 35m^2 +35m -5m -5

= 35 m^2 + 30 m - 5

Answer:

The value of x in this equation is 8.

Step-by-step explanation:

5x - 1 = 6x - 9

Subtract 6x on both sides.

-x - 1 = -9

Add 1 to both sides.

-x = -8

Divide by -1 on both sides.

x = 8

What is the slope-intercept form of the equation of the line that passes through the points (−3, 2) and (1, 5)?

IceJOKER [234]

Answer:

y = 3/4x + 17/4

Step-by-step explanation:

Step 1: Find slope <em>m</em>

m = (5 - 2)/(1 + 3)

m = 3/4

y = 3/4x + b

Step 2: Find <em>b</em>

5 = 3/4(1) + b

5 = 3/4 + b

b = 17/4

Step 3: Rewrite equation

y = 3/4x + 17/4

Answer:

x = 7, -7

Step-by-step explanation:

(2x-1)(3x+2)+x+292

3x - 2x +x = 2 - 1 + 292

(6)x - 294 = 6(x - 49)

Use communicative property of multiplication

Example: (A+B)(A-B)

$Ax^{2} -AB+BA-Bx^{2} =Ax^{2} -AB+AB-Bx^{2} =\\Ax^{2} -Bx^{2}$

49 is the square of 7

x square is the square of x to the power of 1

(x+7)(x-7)
