Since it's literally cut in half, that means the triangle's area is literally half of the rectangle's area. Therefore, if we write it as
the triangle's area (a)=(1/2)*(b) (the rectangle's area) we can multiply 2 to both sides to get 2*a=b. Since a is (2x+10), we can plug it in and use the distributive property (since we just can't add up variables and integers) to get
2*(2x+10)=4x+20=b
Answer:
x=4
Step-by-step explanation:
3(3x+2)=7(x+2) Cross product
9x+6=7x+14 Solve for x
9x-7x=14-6
2x=8
x=8/2
x=4
Answer:
No.
Step-by-step explanation:
This is incorrect because the hot air balloon traveled up to 7500 feet. The distance descended cannot be greater than 7500 feet. Joe's expression tells us that the hot air ballon descended 10500 feet. He is incorrect because 10500 > 7500.
Answer:
2x^2 + x + 4
Step-by-step explanation:
Use Polynomial division.
Answer:
D. A withdrawal of $30 from a bank account
Step-by-step explanation:
When it says magnitude it doesn't matter if it's a positive or negative number.
So it's just asking which number is the greatest which is 30.
I hope my explanation makes sense and helps you out.
