78 degrees right cuz mnp=qst so n would equal s
Answer:
5
Step-by-step explanation:
First multiply 7 and 4
7 * 4 = 28
Then divide 140 by 28
140/28 = 5
Height is 5
Answer:
5x^2 − 2x
Step-by-step explanation:
Let's simplify step-by-step.
=3x + 6x^2 + − 5x + − x^2
Combine Like Terms:
=3x + 6x^2 + − 5x + − x^2
=( 6x^2 + − x^2 ) + ( 3x + − 5x )
= 5x^2 + − 2x
Answer:
5x^2 − 2x
hope this helps!!
Answer:
[See Below]
Step-by-step explanation:
✦ First you have to determine the rule:
✧ The rule is -2
○ 4 - 2 = 2
○ 2 - 2 = 0
○ 0 - 2 = -2
○ -2 - 2 = -4
○ And the rule would go on and on...
✦ And now that you know the rule, you have to determine the next terms:
✧ -6
✧ -8
✧ -10

Step-by-step explanation:
Build a rectangle 12 cm high and 5 cm wide (Paint it). Then a) Find the perimeter of the rectangle. B) Find the area of the rectangle. Aiuda porfis.
Length of the rectangle is 12 cm
Breadth of the rectangle is 5 cm
Perimeter is the sum of all sides. For rectangle it is given by :
P = 2(l+b)
⇒ P=2(12+5)
P = 34 cm
Area of a rectangle is equal to the product of its length and breadth.
So,
A = lb
A = 12 cm × 5 cm
⇒A = 60 cm²
Hence, perimeter is 34 cm and area of rectangle is 60 cm².
