Answer:

#2: -10, 10

-10 < 10

Negative Ten is less than Positive Ten

#3: -12<-7

#4: 10>-3

Step-by-step explanation:

#2: There is a green mark on -10 and 10

-10 has a lower value than 10, so 10 is greater than -10

The inequality above would be written in word format

#3: -12 is lower in value then -7, so -12 would be less than -7

#4: 10 has a higher value than -3, so 10 is greater than -3

An isosceles right-angled triangle is shown.

Bad White [126]

Answer:

$\boxed{x=4}$

Step-by-step explanation:

Area of triangle = 0.5 × Base × Height

→ Substitute in the values

200 = 0.5 × 5x × 5x

→ Simplify

200 = 12.5x²

→ Divide both sides by 12.5

16 = x²

→ Square root both sides

4 = x ∴ x = 4
