Answer:
Step-by-step explanation:
= 7(19) - 142(31) = <em>- 4269</em>
= 7(- 8)(- 9) + 11(2)(- 16) + 21(55)(- 1) - 21(- 8)(- 16) - 7(2)(- 1) - 11(55)(- 9) = <em>1768</em>
= 9.07(2.5)(2.35) + 6.02(3.5)(3.55) + 2.01(- 30.7)(- 1.1) - 2.01(2.5)(3.55) - 9.07(3.5)(- 1.1) - 6.02(- 30.7)(2.35) = <em>647.3561</em>
Answer:
The dimensions of the frame are 15 in x 13 in
Step-by-step explanation:
Let
x ----> the length of the picture
y ----> the width of the picture
we know that
-----> equation A
The area of the picture, including the frame is


so
----> equation B
substitute equation A in equation B

solve for y

solve the quadratic equation by graphing
The solution is y=7 in
see the attached figure
<em>Find the value of x</em>

Find the dimensions of the frame


therefore
The dimensions of the frame are 15 in x 13 in
