Y = –x2 + 4x + 12
y = –3x + 24
so
–x2 + 4x + 12 = –3x + 24
x^2 -7x + 12 = 0
(x - 4)(x - 3) = 0
x - 4 =0; x =4
x - 3 = 0; x= 3
y = –3x + 24 = -3(3) + 24 = -9+24 = 15 (when x = 3)
y = –3x + 24 = -3(4) + 24 = -12+24 = 12 (when x = 4)
answer
(3, 15) and (4, 12)
Answer:
A =.448 ft^2
Step-by-step explanation:
A = b*h
A = 1.4 * .32
A =.448 ft^2
<span>Find
the number with the same value when multiplied together get the result of 2
025.
=> to get the answer, find the square root of 2 025
=> √ 2 025 (the total number)
=> 45 (the number we are looking which is the square root of the given
number.)
Thus, 45 is the number that will be multiplied together will result to 2 025.
Let’s check if our answer is correct
=> 45 x 45
=> 2 025
Therefore, our answer is correct</span><span>

Answer: Cal's answer must be incorrect because the sum of angles is incorrect.
Step-by-step explanation:
The sum of all interior angles of a triangle is 180 degrees.
According to Cal, the three angles of the triangle has magnitude 65, 45 and 60 respectively.
Sum of angles = 65+45+60
i.e. Sum of angles = 170 which is not equal to 180
Hence, Cal's answer must be incorrect because the sum of angles is incorrect.
The answer is 60 to this problem
