Answer:
4x^2 + x
Step-by-step explanation:
just multiply x to each of the terms.
Answer:
<h3>y = 35x</h3>
Step-by-step explanation:
If you notice, point 4 on the x-axis (horizontal) coincides with 140 on the y-axis.
If you multiply x * 35 = 140
x is four.
Answer: ∠1 = 109° ∠2 = 71°
<u>Step-by-step explanation:</u>
If the two angles form a linear pair, then their sum is 180°
∠1 + ∠2 = 180°
(5x + 9) + (3x + 11) = 180
8x + 20 = 180
8x = 160
x = 20
∠1 = 5x + 9
= 5(20) + 9
= 100 + 9
= 109
∠2 = 3x + 11
= 3(20) + 11
= 60 + 11
= 71
<u> CHECK:</u>
∠1 + ∠2 = 180°
109° + 71° = 180°
180° = 180° 
Answer:
Well... "Alphabets" in math, are defined as variables...
And we use variables to show the things that we are multiplying, dividing, subtracting, or adding. Like: Beach balls=B "Tommy has to blow up 20 beach balls before he can go to the beach, his mom offers to help him. How many beach balls do each of them have to blow up?" One equation we could use is "B/2 or B divided by 2" :)
