Here's my step-by-step explanation:
We're just gonna factor.
If your teacher has spoken of FOIL, then he/she has probably said that it means First Outer Inner Last and that it helps with distributing problems like these.
Right, so let's get to it.
Can you see the FOIL method being spread out here? Let's keep going.
Hope this helps, and let me know if I made a mistake! ^_^
Let A = 4 A=4 A=4 cm and B = 9 c m B=9
cm B=9cm. The distance between A A A
and B B B is the absolute value of their
difference: IA-BI=B-Al=14-9..
35 degrees.
Assuming 145 is the exterior angle, the interior is 35. 180-145=35
Add 110 to 35 and get 145 degrees. Which leads the remaining angle 35 degrees
Answer:
127
Step-by-step explanation:
m<PQR and m<RQS are supplementary angles so their sum is 180
3x - 5 + x + 1 = 180 add like terms
4x - 4 = 180 subtract 4 from both sides
4x = 176 divide both sides by 4
x = 44
m<PQR is 3x - 5 replace x with 44
3*44 - 5 = 127
Answer:
The area is just length times width: (4x+5)(3x+10)=12x2+55x+50.
