Answer:
1. B
2. B
Step-by-step explanation:
To find the missing term, find the scale factor between the fractions - the number which multiplies to one to make the other.
1. 7 x __ = 35
7x 5 = 35 therefore 5 is the scale factor. Multiply 15 x 5 = 75
2. 8 x ___ = 32
8 x 4 - 32 therefore the scale factor is 4. Multiply 1 x 4 = 4.

Answer:
25
Step-by-step explanation:
Given the function that represents the amount of mosquitoes as;
M(x) = -(x-5)² + 25
To get the maximum mosquitoes possible, we need to first find x;
At the maximum dM/dx = 0
dM//dx = -2(x-5)
0 = -2(x-5)
-2(x-5) = 0
-2x + 10 = 0
-2x = -10
x = 10/2
x = 5
Substitute x = 5 into the function;
M(5) = −(5−5)² +25
M(5) = 0+25
M(5) = 25
Hence the maximum number of mosquitoes is 25
(a+b)(a-b)=a^2 - b^2
