Base=x+7 Height=x Area=60. 60=((x+7)(x))/2----->60=(x^2+7x)/2
120=x^2+7x X^2+7X-120=0. QUDRATIC FORMULA: -7+/- SQRT(49+480)/2
(-7+/-23)/2... 8 and -15. -15 ISNT the answer because you cant have a negative length. X=8 Base=8+7---->15 Height=8
Answer:
slope = -3 , y-intercept = 9
Step-by-step explanation:
470/7= 67.14......
67.14 was her fee
67.14 * 1.5 = 100.71
100.71 is her hourly rate
Answer:
10 ring boxes
Step-by-step explanation:
First, we need to calculate the total surface area of each cube ring boxes
The surface area of each square boxes = 6L²
Given that L =1.5inches
Total surface area = 6(1.5)²
Total surface area = 6(2.25)
Total surface area = 13.5in²
<em>Since the question is incomplete. Let us assume the total surface area of the shipping box is 135in²</em>
<em></em>
Number of ring boxes he can ship = 135/13.5
Number of ring boxes he can ship = 10
Hence the number of ring boxes he can ship is 10 ring boxes

<u><em>NB: The total surface area of the shipping box was assumed</em></u>
