Answer:
Step-by-step explanation:
First solve the sums that are within the parentheses.
Remember that if the numbers have equal signs then they are added and the same sign is placed.
If the numbers have different signs they are subtracted and the sign of the major is placed
So:
Then we have the following expression:
Remember that by multiplying signs you get:
(+) * (+) = +
(-) * (-) = +
(+) * (-) = -
(-) * (+) = -
Then:
Given : (5x + 8 - 6x) (4 + 2x - 7)
The given question can be written as : (8 - x) (2x - 3)
⇒ 8(2x - 3) - x(2x - 3)
⇒ 16x - 24 - 2x² + 3x
⇒ -2x² + 19x - 24
<u>Answer</u> : Option D
Answer:
s=4.75
Step-by-step explanation:
Just substitute the given variable values into the original equation
s=10•½+½•-2•½²
s=5+-1•¼
s=5+-¼
s=-4.75
The measure of x from the diagram is 15
<h3>Circle theorems</h3>
From the given diagrams, we are told that fg⊥op, rs⊥qr. Given the following parameters
FG = 40,
RS = 40,
OP = 15.
Since the measure of FG is equal to RS, hence the measure of Op will be equal to OQ to have:
OQ = OP = x
x = 15
Hence the measure of x from the diagram is 15

Answer:
x-10
Step-by-step explanation:
you have to do what is in the parenthesis first. Do distributive property to
-(x-8)
-(x)-(-8)= -x+8
now you have 5-(3-x+8)
Do distributive property again
5-3+x-8
x-8+2
x-10
hope this helps ~D~
