The teacher would need 40 centimeters of tape to hang 10 student projects.

Step-by-step explanation:

Given,

Tape used to hang projects = 36 centimeters

Number of projects hanged = 9

We will find unit rate;

9 projects = 36 centimeters

1 project = \frac{36}{9}\ centimeters

1 project = 4 centimeters

Therefore,

Tape needed to hang 10 projects = 4*10 = 40 centimeters

The teacher would need 40 centimeters of tape to hang 10 student projects.

Keywords: unit rate, multiplication

oksian1 [2.3K]
<h3>I'll teach you how to solve 15x ^2 −4x−4</h3>

--------------------------------------------------------

15x ^2 −4x−4

Break the expressions into groups:

(15x^2+6x) + (-10x-4)

Factor out 3x from 15x^2+6x:

3x(5x+2)

Factor out -2 from -10x-4:

-2(5x+2)

3x(5x+2) -2(5x+2)

Factor out common term 5x+2:

(5x+2)(3x-2)

Your Answer Is (5x+2)(3x-2)

plz mark me as brainliest :)

Use the Associative Property of Addition to write an expression equivalent to r+ (h+t). r+ (h+t) = Enter your answer in the answ
svlad2 [7]

Answer:

Associative propertry of addition.

Step-by-step explanation:

The associative property of addition states that:

a+(b+c) = (a+b)+c

It states that we can add numbers regardless of the groups. The sum does not change  irrespective of how the addends are grouped.

We are given the expression:

r + (h + t)

It can be written as:

(r+h) + t

It can also be written as:

r + (h+t) = (r+t) + h = (h+t)+r = h + (t+r)

Whatever maybe the arrangement of r, h and t, their sum will always be equal. We can regroup them in many ways but the sum remains the same.

The sides of a square are all increased by 3 cm. The area of the new square is 64 cm'.
brilliants [131]

Side of the original square is 5 cm.

Step-by-step explanation:

  • Step 1: Let the side of the original square be x. Then side of the new square = x + 3 and Area of new square = 64 cm²

Area of a square = (side)²

⇒ 64 = (x + 3)²

⇒ 64 = x² + 6x + 9

⇒ x² + 6x - 55 = 0

⇒ x² + 11x - 5x - 55 = 0        (Since 6x = 11x - 5x as part of factorizing)

⇒ x(x + 11) - 5(x + 11) = 0

⇒ (x + 11)(x - 5) = 0

⇒ x = -11 and x = 5 (Lengths can't be negative)

Side of the original square is 5 cm.
