Answer:
-25.44
Step-by-step explanation:
(a+b)(a-b)=a^2 - b^2
so
<span>(4x-7)(4x+7) = 16x^2 - 49
answer
</span>16x^2 - 49
Step-by-step explanation:
Simply use the general equation of a circle to obtain its equation given the center. Because radius is 5 units, this may be referred to the 3-4-5 triangle, meaning the point on circumference is 3 units across in the x-direction and 4 units up in the y-direction.
Hello
8y+y-5y = 9y- 5y =4y
or 8y+y-5y = y(8+1-5) =y (9-5) = y(4) =4y
To find<span> the </span>cube root of a number<span>, you want to </span>find <span>some </span>number<span> that when multiplied by itself twice gives you the original </span>number<span>. In other words, to </span>find <span>the </span>cube root<span> of 8, you want to </span>find<span> the </span>number<span> that when multiplied by itself twice gives you 8. The </span>cube root<span> of 8, then, is 2, because 2 × 2 × 2 = 8.</span>
