Used subtraction to solve for plates(p).
The answers are A and E.
The factors are (2x +9)(2x-9). If you solve each one by equaling each one to zero. You will get:
2x+9=0 2x-9=0
x=-9/2 x=9/2
Answer:
The difference in these temperature extremes in Africa is: 147 °F
Step-by-step explanation:
As per the statement:
The highest temperature ever recorded in Africa was 136°F in Libya.
⇒Highest temperature = 136 °F
It is also given that:
The lowest temperature ever recorded in Africa was –11°F in Morocco.
⇒Lowest temperature = -11 °F
We have to find the difference in these temperature extremes.

Substitute the value we have;
= 136-(-11) = 136+11=147°F
Therefore, the difference in these temperature extremes in Africa is: 147 °F
Answer:
77 m
Step-by-step explanation:
The 2 situations are similar , so the ratios of corresponding sides are equal.
let h be the height of the tower, then
=
( cross- multiply )
1.77h = 137.025 ( divide both sides by 1.77 )
h ≈ 77 m ( to the nearest metre )
