Answer:
I believe both A and B are correct
Step-by-step explanation:
X² + 16x + 64 = 0
x² + 2 * x * 8 + 8² = 0
Now, sing the formula (a + b)² = a² + 2ab + b² , we get,
(x + 8)² = 0
Square rooting on both sides, we get,
x + 8 = √0
x + 8 = 0
x = - 8 <== that's your answer!!!
Answer:
angle 3. ( x ) is 136°
angle 4 ( y ) is 44° !!
Step-by-step explanation:
Let angle 3 be x and angle 4 be y
Given, Angle 3 and angle 4 form a linear pair
x + y = 180 [ sum of linear pair angle is 180 ] ... ( i )
Also, The measure of Angle 3 is four more than three
The measure of Angle 3 is four more than threetimes the measure of angle 4.
x = 4 + 3y .... ( ii )
Putting value of x from ( ii ) in ( i )
4 + 3y + y = 180
4y = 176
y = 44
Also, x + y = 180 => x = 180 - 44 = 136
hey there!
7/12 divided by 2/5 is 7/30
first you have to find the reciprocal for 2 / 5 can do that by flipping 2 / 5 you'll then get 5 / 2 now the rest is simple all you have to do is multiply 7/12 by 2/5 so you multiply 7 by 2 and you get 14 that's your numerator 10 divide 12 by 5 and you'll get 60 so now you have 14 / 60 7 / 30 now you simplify and you get
I hope I helped please mark me brainliest
baiiiiiii
Answer: For every 1 can of red paint, the number of yellow paints used by the painter is
and
There are approximately 29 cans of yellow paints for 34 cans of red paints.
Step-by-step explanation:
Since we have given that
Number of cans of red paint = 14
Number of cans of yellow paint = 12
According to question, we have to find that for every 1 can of red paint the painter uses what number of yellow paints;
Since the ratio of red paint to yellow paint is given by

So, for every 1 can of red paint, the number of yellow paints used by the painter is 
Similarly,
If Number of can of red paint is used = 34
So, Number of cans of yellow paint will be

Hence, there are approximately 29 cans of yellow paints for 34 cans of red paints.
