Current temperature = -2°C
Rise in temperature = 15°C
New temperature = (-2 + 15)°C = 13°C
Answer:
No.
Step-by-step explanation:
It has different order of matrices .
For <em>A</em><em>d</em><em>d</em><em>i</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em>or <em>S</em><em>u</em><em>b</em><em>s</em><em>t</em><em>r</em><em>a</em><em>c</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em>, both matrices must have the same number of <u>r</u><u>o</u><u>w</u><u>s</u> and <u>c</u><u>o</u><u>l</u><u>u</u><u>m</u><u>n</u><u>s</u> .
40+90=130
180-130=50
50+130=180
x=130
50+x=180
Answer:
Step-by-step explanation:
<u>Use the property of 45 degree right triangles</u>
- c = a√2, where c- hypotenuse, a = legs
<u>Top diagram</u>
<u>Bottom diagram</u>
It’s going to be 1/2(6^2 + 4) = 20
