Answer: Use the PEMDAS rule
Step-by-step explanation: 0z+3z+5=2(z-3)=
z= -1
you need to do the z numbers all together and the normal numbers together then subtract them to get -1
I hope that I help you
The answer you are looking for could either be 16 or 40. To solve the equation, you would follow the steps of PEMDAS. Since the 2 above the equation is an exponent, you'd first solve there.
Fill in "a" and "b", the equation will now say 2^2 * 3 + 4 = ?. Assuming that the exponent is meant to go with the 2 alone, 2 * 2 = 4. This leaves the equation to say 4 * 3 + 4 = ? Multiply 3 and 4 to get 12, then add 4 to get 16.
OR
Fill in "a" and "b". This time, we're assuming that the exponent is going with 2 * 3 (originally 2a). Multiply 2 and 3 to get 6, then square 6 to get 36. Finally, add 4 to 36 to get 40.
I'm not quite sure where the exponent was meant to go, but I hope this helps!
Answer:
3.6 cm
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2)*h
We know the area of 4.5 and the top is 1 and the bottom is 1.5
4.5 = 1/2 (1+1.5) h
4.5 = 1/2 (2.5) h
4.5 =1.25h
Divide each side by 1.25
4.5/1.25 = 1.25h/1.25
3.6 =h
-15 I’m pretty sure because if u do the math right it’ll be the answer
Answer:
<em>Angle B=90 degrees</em>
<em> </em>
<em>BA^C= 40 degrees</em>
Step-by-step explanation:
<em>Angle B=</em><em>90 degrees (</em><em>right angle =90 degrees</em><em>)</em>
<em />
<em>90+50+BA^C=180</em>
<em>140+BA^C =180</em>
<em> BA^C=180-140</em>
<em> </em><em>BA^C= 40 degrees</em>
<em> </em>
