The sum of -8 and a number is at least 9 what is the equation look like

-8 + x ≥ 9

Step-by-step explanation:

Let's look at your sentence:

The sum of -8 and a number is at least 9 what is the equation look like

Sum is the result of adding

At least 9 means that the number is 9 or greater.

So what you have here is an inequality expression:

Sum of -8 and a number

-8 + x

x here is the "number" since we do not know the value we will use "x" to represent that number.

At least 9

At least means that it is equal or greater, so we use this expression ≥

and so we use put that all together

-8 + x ≥ 9

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
