Answer: Its surface covers 1400 cm²
Explanation:
Since the length of painting = 40 cm
Breadth of painting = 35 cm
Since we know that area of rectangle is product of dimensions.
∴ Area of painting = length × breadth
= 40 cm × 35 cm
= 1400 cm²
∴ Its surface cover 1400 cm².

Answer:
y = m x + b equation of straight line
Slope = (y2 - y1) / (x2 - x1) = (-3 - 1) / ((7 - (-5)) = -4 / 12 = -1 / 3
y = -x / 3 + b since m is defined above
lf y = 7 then x = -5 given
7 = 5/3 + b
b = (21 - 5) / 3 = 16 / 3 = 5 1/3
y = -x / 3 + 5 1/3
Check: Use point x = -5
y = 5/3 + 16/3 = 21 / 3 = 7 correct
Answer:
Step-by-step explanation:
sum of angle of triangle is 180 degree
5x+8x+50degree =180 degree
13x= 180-50
13x= 130
x= 130/13
x=10
5x= 5*10=50degree
8x= 8*10 =80degree
Answer:
6p^3 + 29p^2 + 22p - 21
Step-by-step explanation:
You can find the product of the expression using the distributive property. The distributive property multiplies the terms of one parenthesis into each term in the other parenthesis. Simplify the product that results by combining like terms or terms which have the same base and exponent.
(2p+7)(3p^2 +4p-3)
6p^3 + 21p^2 + 8p^2 + 28p -6p - 21
6p^3 + 29p^2 + 22p - 21
