Answer:
14mn
Step-by-step explanation:
Step-by-step explanation:
5 - 7x = -44
5 + 44 = 7x
49 = 7x
7x = 49
x = 49/7
x = 7
Answer:
264 cm^2
Step-by-step explanation:
Area of a trapezoid = 1/2 (b1+b2) *h
The area of the large trapezoid
b1 = 14 b2 = 25 h = 10+12 = 22
A = 1/2 (14+25) *22 = 429 cm^2
The area of the unshaded trapezoid
b1 = 8 b2 = 25 h = 10
A = 1/2 (8+25) *10 = 165 cm^2
To find the area of the shaded region, take the area of the large trapezoid and subtract the unshaded trapezoid
429 - 165 =264 cm^2
Answer:
Step-by-step explanation:
∠R = 180 - ( 60 + 50) = 180 -110 = 70
So, the largest side is opposite side of ∠R, so it is PQ
Answer:
x(3 + 4)
4(3x + 1)
Step-by-step explanation:
3x + 4x
The common factor is x, so factor out the x.
3x + 4x = x(3 + 4)
12m + 4
The common factor is 4, so factor out the 4.
12m + 4 = 4(3x + 1)
