Step-by-step explanation:
since it is t/2 for the exponent - thas the answer on khan
Step-by-step explanation:
Use the form (a + b)(a - b) = a^2 - b^2:
(2x^4 + 3x^3)(2x^4 - 3x^3) = 4x^8 - 9x^6.
Answer:
£ 537.63
Step-by-step explanation:
original price = 100%
selling price = 100% - 7% = 93% = £500
just do the proportion or ratio

OP = 500 x 100% / 93%
OP = £ 537.634
rounded to the nearest penny and become £ 537.63
A=138° B=180° C=180° D=138°
This is because angle QRS and QTS would equal 180° Bc they are supplementary. So 180-42=138. And since they are supplementary and vertical angles, angle ST would also be 42° and QT would also be 138° because angle RS is 138°
