Answer:
(4x-5)(2x+3)
Step-by-step explanation:
You could always try using the quadratic formula, but in this case it may be easier to expand the trinomial and factor out common terms.
First multiply the coefficient of the
x
2 term, (
8
) with the constant, (
−
15
) (
8
)
(
−
15
)
=
−
120
Now look for two numbers which multiply together to get −
120 and at the same time have a sum of +
2
.
In this case, (
−
10
)
(
12
)
=
−
120 and −
10
+
12
=
2
Using these two numbers I can expand the original expression:
8
x
2
+
2
x
−
15
=
8
x
2
−
10
x
+
12
x
-15
. Now, in this expanded expression, group the first two terms and the last two terms together
(
8
x
2−
10
x
)
+
(
12
x−
15
)
. Now factor out common terms:
2
x
(4
x
−
5
)
+
3
(
4
x
−
5
)
. Notice the common factor is (
4
x−
5)
. So
(
4
x
-5
)
(
2
x
+3
) is the factored form of the trinomial.

Answer:
4x + 5
Step-by-step explanation:
Product means the multiplication of 4 and x, which is 4 × x = 4x.
Now, the meaning of increased by is that we take that an amount and add a specific amount to it. The initial amount is the product, and the specific amount we're adding to it is 5. So the expression would be 4x + 5
Answer:
<h2>x = 27°</h2>
Step-by-step explanation:
From the question ( 4x + 7)° and [5(x - 4)]° are vertically opposite
Since vertically opposite angles are equal we can equate them to find x
That's
4x + 7 = 5(x - 4)
4x + 7 = 5x - 20
Group like terms
5x - 4x = 20 + 7
<h3>x = 27°</h3>
Hope this helps you
Answer and Step-by-step explanation:
To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.
The reciprocal means the the value, but flipped, so will become .
Now we do 75 times /
So, there are 125 total pages in the book.
