Answer:
The answer is 3x^2+7x+2
Step-by-step explanation:
Multiply each term of the second bracket with the first bracket.
We can write:
(x+2)(3x+1)= 3x(x+2)+1(x+2)
By multiplying the terms we get:
=3x^2+6x+x+2
Now simplify by combining like terms:
=3x^2+7x+2
Thus the answer is 3x^2+7x+2....
Answer:
Area = (5 * 6.5)/2 =16.25 sq.yds
Step-by-step explanation:
The area of a triangle is given by half of the product of the base and the height.
Here
base = 5 yd
height = 6.5 yd
Area = (5 * 6.5)/2 =16.25 sq.yds
So her trainer travels 20miles(using the Pythagoras theorem) while she travels 12+16=36 so the answer is 36-20=16
Answer: 169 times
Step-by-step explanation:
Circumference : 64inches
Distance: 300 yards
We know that 1 yard is 36 inches.
300yd*36 = 10800inches
10800/64 = 168.75 but rounding up makes it 169 times.
7.5y - z/9 + 50 + 2y
Okay, so it would be best to organize and simplify this expression: 9.5y -z/9 + 50
Alright, now let's eliminate some answers.
True or false: The constant is 7.5. This is <em>false. </em>7.5 is a coefficient, 50 is a constant.
True or false: The coefficients are 7.5 and -9. This is <em>false. </em>Sure, 7.5 is a coefficient, but -9 is not. Actually, z/9 is also equal to (1/9)z, so <em>technically </em>1/9 is the coefficient.
True or false: The variables are x and y. This is <em>false. </em>Where is x? Nonexistent.
True or false: The like terms are 7.5y and 2y. This is <em>true. </em>When we simplified the equation, we first combined like terms. 7.5y and 2y are like terms and therefore able to be combined. That's how we got 9.5y.
The answer, I believe, is D. Hope this helps!
