a =
b=
Answers
Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side, then compare the coefficients of like terms.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b, compare to - 6x² + 12x - 15
Compare coefficients of x- terms
- 3a = 12 ( divide both sides by - 3 )
a = - 4
Compare constant terms
- 3b = - 15 ( divide both sides by - 3 )
b = 5

A youth group is making and selling sandwiches to raise money. The cost to make each sandwich is h dollars. The group sells 150 sandwiches for a total of (150h+450) dollars. How much profit does the group earn for each sandwich sold?
Answers
Answer:
Profit earn by group for each sandwich sold=$ 3
Step-by-step explanation:
We are given that
Cost to make each sandwich= h dollar
Total selling price of 150 sandwiches=(150h+450 )dollars
We have to find the profit earn by group on each sandwich sold.
Total cost for making 150 sandwiches=[tex]150\times h[/tex]
Total cost for making 150 sandwiches=150 h
Now,
Profit made by group on 150 sandwiches
=150h+450-150h
=450 dollars
Profit earn by group for each sandwich sold=[tex]\frac{450}{150}[/tex]
Profit earn by group for each sandwich sold=$ 3

14. How many odd 2-digit positive integers greater than 20 are there?
Answers
Answer:
40
Step-by-step explanation:
21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99
We will see that there are 35 two-digit odd numbers larger than 20.
How many odd 2-digit positive integers greater than 20 are there?So in each range of 10 consecutive numbers, we have 5 odd ones.
For example, between 20 and 30 we have:
{21, 23, 25, 27, 29}
And from 20 to 100 (we count to 100 because we only care for 2-digit integers) there are 7 sets of 10s
(20 to 30), (30 to 40), (40 to 50), (50 to 60), (60 to 70), (70 to 80), (80 to 90), (90 to 100).
And we know that in each one of these 7 sets we have 5 odd numbers, so we can conclude that there are:
7*5 = 35 2-digit odd numbers larger than 20.

Determine if the three lengths given will be able to construct a triangle or not: 5, 12, 2.
A) Yes, they can form a triangle.
B) No, they cannot form a triangle.
Answers
Answer:
B
Step-by-step explanation:
Using the Triangle Inequality Theorem, two sides of the triangle should always add up to be greater than the third side or it is not a triangle.
5 + 2 = 7 This sum is less than the third side, 12. Therefore, this cannot make a triangle.

Which measurements could create more than one triangle?

B. A triangle with sides measuring 5 inches, 7 inches, and 9 inches
C. A triangle with sides measuring 50 mm and 35 mm and a
nonincluded angle measuring 25°
O D. A triangle with sides measuring 8 cm and 12 cm and an included
angle measuring 85°
Answers
Using rules of congruency, option C. A triangle with sides measuring 50 mm and 35 mm and a nonincluded angle measuring 25°, can create more than one triangle.
What is congruency?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure i.e., the triangles are of same size and shape.
Since part A and B follow SSS congruency, thus for such measures, there can only be one triangle. Similarly, part D follows SAS congruency.
But for part C, there is no congruency as SSA.
