Answer:
a)Numerator has 3 terms
c)Denominator includes a coefficient of 2
Step-by-step explanation:
Given the expression in the question
-10x² + 15x + 3 / (2x² + 4)
<h3>
1) </h3><h3>
Numerator has 3 terms</h3>
Numerator is the upper part of fraction which in this case is -10x² + 15x + 3 and a term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or - sign.
<h3>2) </h3><h3>Denominator includes a coefficient of 2 </h3>
Denominator is the lower part of fraction which in this case is 2x² + 4 and coefficients are the constants by which the variables are being multiplied.
Answer:
31.5 square inches
Step-by-step explanation:
First, you need to enlarge each side with a scale factor of 1.5.
7 inches = 10.5 inches
2 inches = 3 inches
The new sides are 10.5 and 3 inches long. Now, you need to use these side lengths in the area formula of a rectangle.
A = Bh
A = 10.5(3)
A = 31.5 in.²
Answer:
D
Step-by-step explanation:
A recursive formula lets us calculate a term in the sequence by multiplying the previous term by the common ratio r
for the sequence
- 3, 9 , - 27 , 81....
the common ratio r is
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3
Then the recursive formula is
f(n) = - 3 f(n - 1) if n > 1
f(1) = - 3
option D
The answer tou your question is 8 more hours
Answer:
E. 18 children are buying their lunches
F. Rock must pay $50 each month
Step-by-step explanation:
E.
To find a percentage you multiply the number by the percentage;
60 x 70%(0.70) = 42 children brought their lunches
But we need the amount <u>buying</u> their lunches so we would subtract 60 by 42;
60 - 42 = 18 buying their lunches
F.
Again, to find the percentage we multiply it by the original;
$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa
Now we need to find how much Rock still needs to pay for the sofa;
$800 - $200 = $600 more needed to pay for the sofa
Lastly, we must find how much Rock will need to pay <u>each month</u> to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;
$600 / 12 = $50 needs to be paid each month for a year
