Answer:$21.20
Step-by-step explanation:
5.30x and x =4
5.30 times 4 is 21.20
Answer: 6) =approx 156.60 cm
7) =approx 687.68'
Step-by-step explanation:
6. Let the shortest side of the triangle is AB=45 cm ( ∡A=90° so ABCD is a rectangle). The middle side AD=150 cm. The longest side is BD
The length of BD can be calculated using Phitagore theorem because triangle BAD ia right angle.
BD=sqrt(AD²+AB²)=sqrt(2025+22500)=approx 156.60 cm
7. So we can create the model of the situation described in this problem.
The model is right-angle triangle ABC with side AB=520' ,side AC=450', right angle is A. So we have to find the length of side BC .
BC is hypotenuse of triangle ABC. We can find it using Phitagore theorem again.
BC=sqrt(AC²+AB²)=sqrt(450²+520²)=sqrt(472900)=approx 687.68'
Answer:
(3w-5)(w+2)
Step-by-step explanation:
Add w to the other side to make it 3w^2+w-10, from there factor out knowing it would be (3w+a)(w+b) and what makes 10? Surprise only 5*2 and 10*1 and plug them into a and b and see which combination works
