Step-by-step explanation:
area of ∆ = .5*b*h
b= x+5
h= x-5/2
let's do (x+5) * (x-5/2)
x^2+5x-5/2x-25/2
x^2+5/2x-25/2
area = .5x^2+5/4x-25/4
Anna picked 6 apples
Sabrina picked 7 <em>times</em> as many apples.
Multiply the two numbers together
6 x 7 = 42
Sabrina picked 42 apples

Solve your equation step-by-step.
2(x−3)−17=13−3(x+2)
Simplify both sides of the equation.
2(x−3)−17=13−3(x+2)
Simplify
2x−23=−3x+7
Add 3x to both sides.
2x−23+3x=−3x+7+3x
5x−23=7
Add 23 to both sides.
5x−23+23=7+23
5x=30
Divide both sides by 5.
5x/5 = 30/5
x=6

Step-by-step explanation:
(-3,4) and (5,1)
(-3,4) is in quadrant 2 and (5,1) is in quadrant 1. So think of that.

Answer:
The area of a triangle is the space contained within its 3 sides. To find out the area of a triangle, we need to know the length of its three sides. The sides should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m). The formula:
Square feet to square meters: multiply ft² by 0.092903 to get m²
Square yards to square feet: multiply yd² by 9 to get ft²
Square feet to square yards: multiply ft² by 0.11111 to get yd²
Square yards to square meters: multiply yd² by 0.8
