Answer:
∠x = 78
Step-by-step explanation:
∠y + ∠1 = 180
=> 125 + ∠1 = 180
=> ∠1 = 180 - 125
=> ∠1 = 55
∠z + ∠2 = 360
=> 313 + ∠2 = 360
=> ∠2 = 360-313
=> ∠2 = 47
∠1 + ∠2 + ∠x = 180
=> 55 + 47 + ∠x = 180
=> ∠x = 180 - 55 - 47
=> ∠x = 78
Answer:
-1/2
Step-by-step explanation:
The expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The area of the rectangle = length x width
= (3x² + 8x + 7)(7x²)

= 21x⁴ + 56x³ + 49x²
Thus, the expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.

Answer:
72% of students chose burritos
Step-by-step explanation:
first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14
then you would take that number and subtract it from the total of all students: 50-14=36
and then you would take that number and divide it by 50: 36/50=.72
turn that into a percent and you'd get 72%
