Answer:
C. 128 in²
Step-by-step explanation:
We know that the opposite sides of rectangles are congruent, so 8 = 2x. If we divide 8 by 2 and 2x by 2, we get x = 4.
- This means that the other side length, (3x + 4), equals 3(4) + 4 = 12 + 4 = 16 inches
Now, the area of a rectangle is l × w, where l = length and w = width. The dimensions of this rectangle are 8 and 16, so 8 × 16 = 128 in².
It’s 20+40=60
24+37=60 rounding to the nearest 10 is 60
Answer:
Step-by-step explanation:
x = 61⁰
Reason: x + 29⁰ = 90⁰ ( right angles i.e the angles are perpendicular to one another)
x = 90⁰ - 29⁰
x = 61⁰
Given:
Temperature in the morning = 6°F.
By the late afternoon, the temperature had dropped 9°F.
To find:
The temperature by the late afternoon.
Solution:
Temperature by the late afternoon = Morning temperature - Dropped temperature
Using the given values and the above formula, we get
Temperature by the late afternoon = 6°F - 9°F
Temperature by the late afternoon = -3°F
Therefore, the temperature by the late afternoon is -3°F.
