A quadrilateral will be a parallelogram when:
7x+7=21 and (2y-1)^{\circ}=49^{\circ}

So let's solve these equations in order to find x and y:
7x+7=21
7x=21-7
7x=14
x=14/7=2

2y-1=49
2y=49+1
2y=50
y=50/2=25

Solution: x=2 and y=25

Since there is no picture, find here-under the conditions that a quadrilateral becomes a parallelogram:
( All are either or)
1- opposite sides should be congruent
2- opposite angles should be congruent
3- opposite sides parallel
4-The sum of 2 adjacent angles to equal 180°
5 the 2 diagonals intersect in their middle

With any of these conditions, if confirmed, you can conclude that the quadrilateral is a parallelogram (By the way a rectangle is a parallelogram with one angle =90°

How do I find B in y=mx+b?
mixas84 [53]
If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.

An example of the equation would be

y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept

How do you solve for x in this problem?
irina [24]

Answer: you will use the cosine rule

Step-by-step explanation:

x^2=11^2+8^2-2(11)(8)xcos(16)

x^2=185-169.18

x^2=15.8

What is the product of 9 radical 5 and 5 radical 10 in simplest radical form?
tatuchka [14]

Answer:

Step-by-step explanation:

(9√5)   (5√10)

The leading interger product is found by multiplying 9 and 5

The leading integer product is 9*5 = 45

The radical product is (√5*10

Factor 10

radical product = √5*2*5

There are 2 fives underneath the radical. Take one out and ignore the other

radical product = 5√2

The 5 now multiplies by 45 and √2 becomes part of the answer

5*45√2

225√2
