answer: 28: 4
21: 3
70: 10
step-by-step explanation:
divide 28 by 4, and of course, do to the bottom what you do to the top. 4 divided by 4 is 1, and 28 divided by 4 is 7.
7: 4.
then, multiply by the number of smoothies.
for 3, it's 21: 3.
for 10, it's 70: 10.
Answer:
576 Units
Step-by-step explanation:
The way your teacher wants you to do it:
1. We know that multiplying a length by four gives us the perimeter of a square.
1a. Thus, we multiply the given length by four. 4(10x+4)=40x+16
1b. We know the perimeter is 96. So: 40x+16=96
2. Solving for x, we get x=2
3. Plugging our solved x into the given length (10x+4), we see that the length of a side of the square is 10*2+4=24.
4. We know that the area of a square can be found by squaring the side of a square.
4a. 24*24=576.
5. The area is 576 units.
--------------------------------------------------------------
Easier Solution:
1. We know that the perimeter is length*4.
2. We set L to length.
2a. 4L=96
2b. L=24
3. We know that the length square is area.
4. 24*24=576.
The graph of a quadratic function is a parabola. The axis of symmetry<span> of a parabola is a vertical line that divides the parabola into two congruent halves. The </span>axis of symmetry<span>always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the </span>axis of symmetry<span> of the parabola.</span>
