Concept: Solution of the given attachment is based on the addition of two vectors as given below.
Consider two vectors P and Q, then resultant of these two vectors is given as,
R = P + Q
To find the addition of G & H vectors. That is G + H =?
In the given figure;
Vector A = - Vector G because both are in opposite directions -----(i)
From the figure,
A + H = F --------------- using the given concept ---------(ii)
Now, shall replace the value of A from equation (i) in equation(ii)
- G + H = F
or, G + (- H) = - F
Since the vector addition of G & H is not equal to F.
Hence, the given statement G + H = F is False.
Answer: 17mm
Step-by-step explanation:

Solution :
The null and alternative hypothesis is given by


Assume that the level of significance, α = 0.05
The t-test statistics is, t = 1.484
Degree of freedom :
df = n - 1
= 14 - 1
= 13
The P-value is given by
P-value = 2P (T>|t|)
= 2P(T>|1.484|)
= 2P(T>1.484)
= 2(=T.DIST.RT(1.484,13))
= 0.05

Step 3
EXPLANATION
The given polynomial expression is:

Fatau correctly expanded the parenthesis in the first step.

Fatau also correctly grouped the like terms to obtain:

Fatau committed a mistake at the third step.
Instead of obtaining,

He mistakenly got:

Answer:
5 (x + 1) (4 x^2 - 5 x + 3)
Step-by-step explanation:
Simplify the following:
(4 x^2 - 5 x + 3) (5 x + 5)
Factor 5 out of 5 x + 5:
Answer: 5 (x + 1) (4 x^2 - 5 x + 3)
