Answer:
a). 5x - 12 b). 2x(4x + 3)
Step-by-step explanation:
a). 7(x - 2) - 2(x - 1)
= 7x - 14 - 2x + 2
= 5x - 12
b). 8x² + 6x
2x(4x + 3)
Answer: 235
Step-by-step explanation:
Total score if he average 205 = 205 * 4 = 820
Score needed on 4th game = 820 - 210 -185 - 190 = 235
Answer: The area of the triangle is: " 2v⁴u² square units" ;
or, write as: " 2v⁴u² units² " .
______________________________________________________
<u>Note</u>: The formula/equation for the area, "A", of a triangle is:
A = (1/2) * b * h ; or: A = (b * h) / 2 ;
______________________________________________________
in which: "A" = "area" ;
"b" = "base length" ;
"h" = "[perpendicular] height" ;
______________________________________________________
We are asked to solve for the area, "A" .
We are given: "b = 4v³ " ; "h = vu² " ;
So; to find the area, "A", of the triangle, we plug these given values into the formula; and solve/ simplify:
____________________________________________________
A = (1/2) * b * h ;
A = (1/2) * (4v³) * (vu²) ;
A = 2v³ * vu² ;
A = 2v⁴u² square units.
Answer: The area of the triangle is: " 2v⁴u² square units" ;
or, write as: " 2v⁴u² units² " .

Discount %= 10%
Discount= x × 10%= x/10
Price after discount =x-(x/10)= 9x/10
But, given price after discount = rs 450
9x/10=450
9x=4500
x=4500/9= rs 500
Answer:Division allows us to divide or 'share' numbers to find an answer. For example, let's consider how we would find the answer to 10 ÷ 2 (ten divided by two). This is the same as 'sharing' 10 sweets between 2 children. Both children must end up with the same number of sweets.
