Answer:
First answer: The sum of the two angles equals 70 degrees.
Second answer: The complimentary angle is 45.6, and the supplementary angle is 135.6.
I hope this helps! :)
Answer:
1. x^2-36
X^2-6^2
(X-6)•(x+6)
3. 16y^2-25
4^2 Y^2-5^2
(4y)^2-5^2
(4y-5)•(4y+5)
5. 9a^2-121
3^2 a^2-11^2
(3a)^2-11^2
(3a-11)•(3a+11)
6. 196-x^2
14^2 -x^2
(14-x)•(14+x)
8. 36c^2-d^2
6^2 c^2 -d^2
(6c)^2-d^2
(6c-d)•(6c+d)
11. 1-4a^2
1^2- 2^2 a^2
1^2-(2a)^2
(1-2a)•(1+2a)
-9 ≤ x ≤ 4
it is less than or equal to -9°F, but also less than 4°F
Hope this helps
The force the same object will exert if it accelerates at a rate of 7 m/s² is 35N
From the question,
We are to determine the force the object will exert.
From the information,
Newton’s Second Law of Motion states that the acceleration of an object is directly proportional to the force exerted on the object
Let acceleration be a
and
Force be F
Then we can write that,
F ∝ a
Then,
Introducing the constant, mass, m
We get
F = ma
Now, we will determine the mass of the object
F = 15 N
a = 3 m/s²
Putting the parameters into the formula, we get
15 = m × 3
∴ m = 15 ÷ 3
m = 5 kg
The mass of the object is 5 kg.
Now, to determine the force the same object will exert if it accelerates at a rate of 7 m/s²
That is,
a = 7 m/s²
and
m = 5 kg
Putting the parameters into the formula, we get
F = 5 × 7
F = 35 N
Hence, the force the same object will exert if it accelerates at a rate of 7 m/s² is 35N

Step-by-step explanation:
x² + 4x - 9
= (x + 2)² - 13
a = 2, b = -13.
