Answer:
Step-by-step explanation:
The figure consists of 2 rectangles.
<u>Rectangle 1 Area:</u>
Length = 5 cm
Width = 2 cm
Area = Length * Width
A = 5 * 2
A = 10 cm²
<u>Rectangle 2 Area:</u>
Length = 4 cm
Width = 2 cm
Area = 2 * 4
A = 8 cm²
<u>Area of the whole figure:</u>
= Rectangle 1 + Rectangle 2
= 10 + 8
= 18 cm²
Hope this helped!

Answer: A. The value of his investment decreased by 16% during this time period.
Step-by-step explanation:
Here the initial amount = n
Final amount after 1 years = 0.84n
The total change in the initial amount = n - 0.84n = 0.16 n
=
Thus, the amount is decreases by 16% in one year,
⇒ Option A is correct.
Answer:
x = - 4, x = -
Step-by-step explanation:
Given
3x² + 14x + 8 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 + 8 = 24 and sum = + 14
The factors are + 12 and + 2
Use these factors to split the x- term
3x² + 12x + 2x + 8 = 0 ( factor the first/second and third/fourth terms )
3x(x + 4) + 2(x + 4) = 0 ← factor out (x + 4) from each term
(x + 4)(3x + 2) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = -
