When simplifying x^3 · x^2, the exponents are added together. True False

1 answer:

8 0

When multiplying exponentials, there is a rule that states if the bases are the same, we add the exponents together.

In this problem, the two bases that are being multiplied are the same, x.

Therefore, we will add the exponents: x^3 • x^2 = x^5.

The correct answer is true. The exponents are added together when simplifying this expression.

Answer:

x =12

Step-by-step explanation:

The two angles are complementary, so the add to 90 degrees

5x+1/2x +24 = 90

Combine like terms

5 1/2 x +24 = 90

Subtract 24 from each side

5 1/2 x = 90-24

Change the mixed number to an improper fraction

11/2 x = 66

Multiply by the reciprocal 2/11 on each side

2/11 *11/2 x = 66*2/11

x = 6*2

x =12

(12 divided by 3) 2 – (18 divided by 3 2)) < (4 divided by 2)

gladu [14]

Answer:

$(12 \div 3)(2 - (18 \div 32) \\ = 4(2 - \frac{19}{16} ) \\ = 4( \frac{23}{16} ) \\ = \frac{23}{4} \\ since \: (4 \div 2) = 2 \\ \frac{23}{4} is \: not \: < 2 \: but \: its \: > 2$

Line 2x-4y-7=0 meets the x axis at point (k,0). Find the value of k

kolbaska11 [484]

K=4
add seven on both sides
2x-4y=7
add 4y on both sides
2x=7+4y
divide 2 on both sides
x=7+4y/2
plug that into original equation
2(7+4y/2)-4y-7=0
7 and 4y cancel out
2(2)=0
4=0
