Answer:
49
Step-by-step explanation:
the line joined by midpoints of sides is called midsection
which is parallel to the third side and is half its length
so (5x - 26) * 2 = 9x - 37
10x - 52 = 9x - 37
x = 52 - 37
x = 15
so PQ is 5x - 26
= 5*15 - 26
= 75 - 26
= 49

For f(x) = 2x + 1 and g(x) = x2 - 7, find (f + g)(x).
Answer:
(f+g)(x)=x²+2x-6
Step-by-step explanation:
(f+g)(x)=2x+1+x²-7
collect like terms
(f+g)(x)=x²+2x+1-7
according to mathematics x² is not a like term of 2x so don't add the them
(f+g)(x)= x²+2x-6

He says that the probability that the sweet will be red is

(a) Show why the probability cannot be
Using the probability concept, it is found that since the number of red sweets would be a decimal number, the probability cannot be [tex]\frac{7}{10}[/tex]
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem:
In total, there are 8 + n sweets in the bag.Of those, n are red.The probability of red is:
[tex]p = \frac{n}{n + 8}[/tex]
Supposing [tex]p = \frac{7}{10}[/tex], we solve for n:
[tex]\frac{n}{n + 8} = \frac{7}{10}[/tex]
[tex]10n = 7n + 56[/tex]
[tex]3n = 56[/tex]
[tex]n = \frac{56}{3}[/tex]
[tex]n = 18.67[/tex]
Since the number of red sweets would be a decimal number, the probability cannot be [tex]\frac{7}{10}[/tex]

Answer:
x=−1 or x=−9
Step-by-step explanation:
x2+11x+10=x+1
Step 1: Subtract x+1 from both sides.
x2+11x+10−(x+1)=x+1−(x+1)
x2+10x+9=0
Step 2: Factor left side of equation.
(x+1)(x+9)=0
Step 3: Set factors equal to 0.
x+1=0 or x+9=0
x=−1 or x=−9
