Answer:
11
Step-by-step explanation:
Area = LW
We know that the w = 2
We are told that the L (length) is three less than an unknown number so that mean L = (x - 3)
We are then told that the area = 22 square inches.
Area = LW
22 = (x - 3)2
Now solve for x
22 = (x - 3)2
Distribute the 2
22 = 2x - 6
22 + 6 = 2x
28 = 2x
28 / 2 = 2x / 2
14 = x
x = 14
Now take 14 and subtract 3
14 - 3 = 11
Unknown number = 11
Area = LW
L = 11
W = 2
Area = 22
11 * 2 = 22
Find three different integers that have a sum of -12: -4 + -5 + -3 = -12. The integers are -4, -5, -3.
In football(yellow text question): Yes, they did earn enough yards to get a first down. If they have a chance to get 10 yards closer to their goal and Matt’s team gained 8, lost 4, and then gained 7. In total Matt’s team has gained 11 yards allowing them to advance. Since 8-4+7 is 11 (8-4 is 4. 4+7=11).
Find two different integers (purple text question): -70 + -2, together they have a sum of -72. The number sentence is -70 + -2 = -72.
Desert Question(teal text question): the difference between the two temperatures is 86. 136- -50 is 86. You subtract -50 from 136 because -50 is a negative.
Answer:
(f×g)(x) = 2x³ +x² -14x -7
Step-by-step explanation:
(f×g)(x) = f(x)×g(x) = (2x +1)×(x² -7)
= 2x(x² -7) +1(x² -7)
= 2x³ -14x +x² -7
(f×g)(x) = 2x³ +x² -14x -7
Answer:
Mr. Terry has $36.60 left after these purchases.
Step-by-step explanation:
1. Multiply the amount of glue sticks purchased by their singular cost.
24 x 1.15= 27.6
2. Multiply the amount of pencil packs purchased by their singular cost.
10 x 0.58= 5.8
3. Add the solutions.
27.6+5.8=33.4
4. Subtract 33.4 from 70.
70-33.4=36.60
