Just multiply the first term in the first parentheses by the two other terms in the second parentheses. Then do the same thing with the second term in the first parentheses.

In other words: (a + b)(c + d) = ac + ad + bc + bd

(2x + 5)(3x + 4) = (2x)(3x) + (2x)(4) + (5)(3x) + (5)(4) = 6x^2 + 8x + 15x + 20

Then combine like terms.

6x^2 + 8x + 15x + 20 = 6x^2 + 23x + 20

So, 6x^2 + 23x + 20 is the answer.

Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of
pochemuha

Answer:

Answer: Osvoldo did not meet his goal.

Step-by-step explanation:

Total carbohydrate ate by Osvoldo = 220 g

carbohydrate from grains = 55 g

Percentage of carbohydrate of grain is

\begin{gathered}=\dfrac{\text { carbohydrate taken from grains}}{\text {Total carbohydrate}} \times 100\\\\= \dfrac{55}{220} \times 100= 25 \%\end{gathered}

=

Total carbohydrate

carbohydrate taken from grains

×100

=

220

55

×100=25%

Goal of getting carbohydrate from grains = at least 30%

but he ate only 25% of carbohydrate

Hence, Osvoldo did not meet his goal as he ate less carbohydrate than his goal.
